And four years later I can still say the same thing. You're the lifeguard of poor Ford owners who are treading the cesspool of modern automotive engineering . Thanks so much! Mark 2007 Lincoln navigator, 5.4L 3v
07 Explorer, 40mph in OD plus a light load created violent jerk. Independent wanted to pull trans, rebuild/diagnose for $3000. Took to dealership was told #5 needs COP and plug. A few more of your videos about the dreaded 3V plug and less than $500 later runs perfect. Thanks for all the great videos!
thank you so much for this video. this is exactly what my ford expedition is experiencing. this saturday my mechanic will be changing the spark plugs and coils
FordTechMakuloco: THANK YOU! THANK YOU! THANK YOU! Thank you SO much for this video! I was having a nearly IDENTICAL problem with my vehicle (Nissan Frontier). I had taken a long trip, and on the way home, my vehicle was doing the same exact thing, at the same speed range. I was agonizing over what might have been a nearly $6,000 repair/replacement for a transmission. Luckily, last night, I came across your video, so I watched the whole video. Today, I did use a scan tool, and, SURE ENOUGH, I found misfire events on one cylinder. I pulled the coil pack on that cylinder, and the coil pack assembly was broken. Since my vehicle is high mileage and 8 years old, I replaced all the coil pack assemblies. My vehicle runs great now!!! I spent $400 instead of potentially $6,000. Again, THANK YOU!!!! (I am going to share your video on TH-cam, hoping it can help some other people, too)
@@jacobadams8073 ...It is possible. The best way to find out is a scan tool. Another very quick way is to pull each coil pack and physically check each one for damage/excessive wear. This would eliminate or possibly confirm the jerking. One last thing: check the cleanliness of your throttle body assembly AND your MAF sensor. Good luck, but best bet is a scan tool.
Someone told me it could be my catalytic converter. But I asked my friend to check it out and he told me I need knew coils and spark plugs and it’s crazy because my check engine light was blinking like the video and would shut off after four blinks. Then went home and left to buy a code reader and it had 3 misfire codes 0300 0302 and 0304. It’s just crazy how my friend knew what potentially could be my problem for power loss and thanks to this video I have hope 🙏
05 Ford F350 5.4 3v Truck was doing that and eventually was throwing code for cylinder 5 and 6 misfire p0300 p0305 p0306 Load on my scanner at idle was at 39% timing was reading from 15 to 45 rough idle and rough start up . Was shaking like crazy. Under load flashing light and goes away when you let go. All plugs and coils checked out good no water or anything else in the holes. Left side cover off and it turned out to be #6 exhaust valve spring was broken. Well while in there already did complete timing job and all following your instructions. Couldn't have done this without you. Your work is much appreciated. Thank you
this was the video that i used to repair my issue same problem no mechanic was able to find the issue until i had an friend that had an ford IDS program and showed him this video and agree that cylinder 5 was causing the misfire .replaced the coils on all and spark plugs i have used pulse star. PROBLEM FIXED . THANK YOU!!!!!!!
Thank you very much...you save me a transmission job...had this same misfire since Christmas..jerking and slamming. And it was a dead mis...one coil.was totally dead..change all 4
THANK YOU VERY MUCH My truck is Nissan pathfinder 2001 2WD has exact problem for months,i thought that is transmission problem,after watched your video last night i run to auto parts next day and get new set of sparkplug Bosch.wow,power gain and down shift seem like is gone,a very very slightly some time,now i just need clean MAP sensor and re-adjust throttle position sensor too.Thank you again.
And four years later I can still say the same thing. You're the lifeguard of poor Ford owners who are treading the cesspool of modern automotive engineering
I want to tell you thank you so much for this video it went out an back to Ford dealership.First trip did reflash ,on second trip it was throwing codes P0717 an U0100. .. they changed both sensors out picked vehicle up thinking its fixed.No still missing feeling like transmission slipping. .....hooked up to scanner no codes.Had them hook computer an drive it different story misfire on coil #1 an #4 .......so going to fix end of this week an replace all plugs. FORD FLEX 2009 lets hope this does it!!!!;)
Perfectly explained the issue I had with my 3.5 mkx. Took two Ford dealers to diagnose. Thankfully the second dealership had a thoughtful tech who took my vehicle home and drove it for awhile with the scanner on it and finally diagnosed it. Now I recognize it happening again. This time is a full on tune up.
Thanks very much.. I thought it was my transmission because I had gotten new engine mounts and I sometimes would feel that hard jerk on the engine... and the only codes that came on were fuel injection codes .... The more you know
Hi Makuloco I just got me a project 06 F-150 5.4 Triton V8. 77k miles and it misfires under load. The repair is straight forward (new spark plugs and ignition coils). If I want to advance my auto repair skills I need a scanner to learn how to diagnose like you did in this video. I was recommended the Autel MaxiAp200 and FORScan, but I rather get a recommendation from an actual Ford mechanic that has extensive knowlegde on the Triton V8. Thanks in advance!
Hi thanks for you video it stopped me from removing my transmission which i was about to start removing in an hour my 99 windstar started to shudder when light acceleration especially on hills or loaded van with the ac on and hard up/down shifts between 1st - 2nd especially when warmed up . I started to see these problems after my engine ceased on me due to the lower intake manifold gaskets leaked i figured it out after it ceased and started opening up the engine and found most of the water in cyl 2. to startup the engine I watched a youtube video where the guy sprays wd 40 into the cylinders and cranks the engine by hand and it worked for me but i didnt bore out or replace any piston rings currently i dont have any codes but my scanner does show a slight percent of cyl 2 misfire. it does seem the shudder gets a little better when i use thicker oil instead of 5w20. thinking the transmission was bad i added the lucas transmission fix into the transmission i dont have any shuddering or hard shifts now but it seems i dont have enough power when acceleration i was still in doubt that its the transmission or the TC, i also was in doubt that i shorted the tcc solenoid for some reason as my brake light switch wire had a loose connnection as i read a post saying that the brake switch has to do something with the tcc solenoid, but that doesnt seem the case now after watching your video now i think i will have to start digging into the engine check the cyl pressure etc.. but still i would ask you to recommend me where to start engine? or transmission? thanks
2009 ranger same harsh miss, only in overdrive going up a hill when the trans should downshift. Tested everything. This happened 1 year after changing spark plugs with NGK. Replace NGK with Motocraft, same issue. Finally replaced plug wires and problem solved, and I should have done this before changing the NGK spark plugs. NEVER had an issue with NGK on any vehicle or equipment I have used NGK spark plugs on. Even Ford with no codes couldn't find it, except that I should have the trans fluid changed. At $250 less tax I am glad I did my own testing. Hard miss as Brian has said in another video is usually seconday ignition. He was bang on with that.
A lot of people don't know that the Alternator can also cause a car to jerk....I had this experience before.....what happens is, your car is losing power and if the alternator is bad or has bad voltage being sent between the battery and distributor cap, the power won't get sent properly to those other parts like the spark plugs which would misfire.
I've been experiencing jerks for about 8mo now, when accelerating between 25-35mph, and also while maintaining a speed of about 45mph. No lights on the dash, and no codes thrown... until yesterday. Check engine light came on, then battery light. Got the battery tested, and they said my voltage regulator is faulty. I've been wondering all day if the two are related?
Good info. My 08 F-150 5.4 is doing this and I first thought it was trans.. It almost never fails, not through all rpms and gears but always at around 1200 RPM between 40-50 mph with any pull on the engine It starts jerking hard repeatedly. If I stab the gas and it pulls harder It still noticeably does it and the check light starts flashing just as it does here. Now to see if I can afford to have it checked out..
thanks for this video. My problem is the same, but i have a 5.4l and I believe it was never serviced while owned prior to me... it is sad how people take advantage of others.
I have a ford Ranger with a cylinder 4 misfire code and a shake and occasional jerk. I replaced the plug wire and coil pack. It seems to run better with no misses so far, but the dead miss is so intermittent it is hard to tell if that is the fix. Thanks for the video!
Hey man, sometimes after driving for a little while 20mins or so when i put my foot on the acclerator, the exhaust sounds louder and discontinuous ( sounds like small explosions after each other). This sound goes straight away when I restart the engine strangely! could this be due to engine misfire or somethung else? But as i said it doesn't always come on and goes away when i restart the engine! any ideas or suggestion is much appreciated ps i dont get any dashboard lights
Had this happen on my mom's '99 Mustang GT 4.6L 2v/auto trans. Felt like trans stutter between 3rd and 4th (40~45mph) during light acceleration. Checked trans fluid;ok. Had her take it to our her local Ford dealership and they told her it was a bad coil on cyl #1. Didn't make any sense to me since it only occurred as stated. In my way of thinking I figured I should have also felt it during WOT but didn't. But I went ahead and temporarily swapped in a spare known good coil from my '06 GT 4.6L GT (swapped the coil boots too). Noticed that there was dried out dielectric grease in the original boot and tip of coil spring and cleaned them up. Test drove it and no stuttering. Hmmm. Swapped the coils back just to be sure. Again no stuttering. Must have been poor contact between the tip of the spark plug and the coil tip (solid tip on spring). Though the tech was correct in diagnosing a misfire he was quick to say it was a failed coil which they wanted to charge $150 to replace.
My 2004 Acura TL did exactly what he was showing in the video. Cars parked at home right now friend of mine looked at codes and it was random misfire p0300 and said all he cylinders were misfiring. Gonna do a comparison test hoping it’s something little
I've been driving with bad ignition coils, and have had the symptoms you describe at the start. But those are actual downshifts, due to the lack of power in the engine.
Hard shift 1-2...changed shift accumulator, MAF sensor, VSS, transmission fluid and no luck. Havent changed TPS because i feel you have to recalibrate it. Ive also searched around and read spark plugs/wires cause mis-fire which is causing the hard shift 1-2.
I recently took my car to the shop with a misfire on #5 in a Cadillac DeVille DTS. Now they have took the ground wire routed to the #4 & 5. Now transmission switching horrible. I believe they burned out the ground wire.
I have a 2011 f350 6.7l. I need to replace the solenoids in the tranny and was wondering if you could let me know the best way to replace them. Seen the video you replacing the tranny fluid and seen the solenoids and just wished you had a video on replacing them too.
Aloha, love your channel and approach to difficult, hard to fix issues on Ford's. I have a1990 Econoline with a hard miss and shuddering. The van sits 6 months out of the year. recently I replaced the distributor, plugs, wires, coil. What are the odds that the ecu has leaking capacitors contributing to this?. Is this more difficult to diagnose on an OBD1 system. ? any input would be appreciated.
I have a 2005 Ford Freestyle. The symptom is that it shudders while driving and at times a it shuts off while driving, but not all the time. I noticed that the issue occurs when i filled the tank. Once it drops to half a tank it drives great. I have replaced (Throttled body, EGR, Computer, 1 coli for miss fire on cylinder 3, Fuel Filter, Fuel Pump) and still have the same symptom. On a Ford blog page. The Ford tech says that it is the Throddle body but still have the problem. Any idea on what it might be? I did get a new AC system for the car. It seemed that once i got a whole new AC system. This problem occurred after 2 month's after the AC system was installed.
my 05 mustang has been running poorly lately kinda similar to this. i get the flashing check engine light usually when i try to drive the car hard as in push it to red line and make it shift under power but instead it won't shift until i let off and will usually flash the check engine light. first i was thinking bad transmission but after seeing this I'm thinking maybe it really is a misfire that is my main issue. the car doesn't usually misfire under normal driving but i went out after watching this and did notice if i put my hand on the intake manifold i can feel an irregularity in the idle like a small misfire is going on. going to check plugs and wires in the morning and compression test and go from there.
hey i got a question for you! i have a 2015 ford escape 2.0 EcoBoost with 122k. recently when i first start my car and i usually let it idle for about 3 minutes and i put it in drive and the car jolts a little bit! if i put it in reverse or neutral its all smooth! once the car warms up everything is smooth like coming out of a store start the car put it in drive and its smooth only when i first start my car, my transmission was rebuilt at 53k and now has 122k on it, last week i did do a transmission drain and fill on it and the transmission fluid was dirty and black! but it did have a little red color to it! and the transmission fluid didnt smell burnt. it seemed to fix the problem start the car in the morning put it in drive all smooth! i think the problem is coming back when i put the car in drive its very slight jerk, do you think i should do another drain and fill on the transmission to get more of the dirty fluid out? any advice? oh yeah no check engine light on.
I have cylinder 4 & 2 misfire with map sensor code and shuddering at 40 m.p.h. in 3rd or overdrive. In 2nd it will misfire but wont shudder. What do u think? Thanks for advice. Its a 2005 ford escape with 3.0. Engine light is on.
I have a 2008 Mercury Mountaineer V6 4.0L and I am having a random misfire issue on cyl 5 as well as "hard shifting" on 2nd and 3rd gear. I'm not sure if they are the same issue or separate. Neither issue is every time. Recent maintenance I've done includes water pump, harmonic balancer, belt, plugs, and leads. The misfire seems like it could be the EGR? I am getting both negative and postive readings on my EGR_ERR, telling me it isn't always moving the amount the computer is calling for. Maybe I'm going down the wrong path... Any ideas? Also, trying to figure out if my hard shifting is a misfire or not. My misfire will go away after shutting down the vehicle and restarting it. Could it be a sensor? Thats is what I am leaning towards...
Ford Ranger 2014 model 2.2l 4x2 (manual tranny, turbo). The problem is, when at 2nd gear or 3rd gear and accelerating from a running stage or climbing it's power is so weak, if rpm is below 1500 it doesn't have power on it, it just slowly picking up and picking up power even if it's already floored. It's so weak it feels like stalling if you have not enough propulsion goin up or if the car you are following suddenly drops speed then you have to change to the lower gears immediately or press clutch then rev it or else you will stall. But then, when rpm finally gets past 2k, it will suddenly picks up power like a a multiple vtec-like power just kicks in. The power delivery is not smooth. Slow acceleration then only picks up power at certain rpm. I replaced all filters already (Fuel filter, Engine Air intake filter) I also changed oil on engine, transmission and even the rear axles with all-AMSOIL fluids. I also asked a friend to clean the EGR. I also replaced the turbo hose in the top. I also added an TECHRON Diesel additive in my last fuel fill to clean injector and fuel lines. Yes I feel a little bit of improvement after all of these cleaning and stuff, but the uneven power delivery and poor low rpm power is still there, it's still bothering me. It's not like that before, I tried two trucks of the same model and specs from a group and they does not act like they were smooth and torqy. It's not normal. What should I check? Shall I clean the exhaust? Catalytic, does it have catalytic or something? At higher speeds no problem, it's a fast truck when it's already at speed. One thing I am noticing is when accelerating the sound also has a tractor-like sound effect if it's accelerating and the tractor sound effect goes away when it gets to speed already. But pressing gas and revving when parked does not create that sound. the sound only appears when accelerating.
shifting is also not smooth, there is a jerk when shifting to other gears.. harsher on downshift. No matter how good rev match I do, it still not smooth transition of gears. No check engines in the Ford Ranger.
Got a 2002 ford super crew 5.4 triton. Hit a big bump and it either dies or the instrument panel ac and all goes dead then comes back on. Any ideas what i got going on.
I recently bought a 04 freestar and it has been trouble since day one the only code that comes up is the coil pack so 3 coil packs and new plugs and wires later it still idles rough bogs down and has no power I tried to go uphill in it the rpms were at 3000 and it was barely going 15mph I'm at a loss I just don't what else it could be
got a 96 2.3 ranger. 5 speed. everytime I hit a bump it sort of bucks. it wants to die whenever it happens. I push the clutch in, and it's fine going over bumps. any ideas?
I have a 2003 Toyota solara. When I drive and am coasting my RPM’s will fluctuate and it feels like my transmission is downshifting hard. Literally feels like a jump. Do you think this could be the cause? Thanks.
I have 2005 f250 with the 5.4 3 valve. I replaced all the coils. I pull a trailer with it (5500 lbs) and while accelerating at high rpms it hesitates and shudders a little or no power. I was thinking I may have a fuel issue or injector issue? 200,000 miles, Just turned over this weekend.
Hey in my 08 Tundra 5.7liter the truck at 30mph to 40mph when I coast and let off the acceralater the truck downshift pretty fast and I have to give it more gas to keep going is that normal
I get zero lights. Ive got the 4.0, 03 explorer. It has violent bang when going up a hill or on a pull? Ive had the drive line looked at. Full compression on all cylinders. No lights at all. We did new bearings and hubs and the transfer case seems good. Rear gears seems good no metal. Its got 169k miles. Ive had it at an independent shop with no success but have an appointment next week for at the Ford service. Any help would be greatly appreciated.
I have a problem like this in 2004 5.4 3v F150. Its the no codes thing that is confusing local shop. I will be driving along and all the sudden truck feels like it hits dead spot then runs like nothing happened. Changed coils and engine feels stronger but still does this. Again no codes. What should I tell them to look for?
I have a 2008 f150. The truck is confusing me. When I am going down the road in first and second gear I am fine but when it shifts into third and rpm is up to 1500 it starts jerking and while truck is shaking/vibrating. I rev up to 2000 rpm and it stops. The only thing I can think of is that there is a possible warped rotor or something wrong with the drivetrain. Any thoughts?
HELP PLEASE!!!! I changed the coil and spark plug on my F150 2000 4.6l but still get a misfire code. I forgot to blow the chamber out though, no oil found but could it be dirty????? Thanks
2009 Flex. I changed the plugs and coil packs 5 months ago and everything was running great. Until now. It feels like 2 cylinders are cutting out. What could cause them to go bad so quickly?
My wife 2007 Edge Sel awd 3.5L v6 suv has tow package & I think sport as well...(I think), Amy way just got Code P0303 cylinder 3 misfire. An the s7v does jerk at times so I am wondering if what you speaking upon here applies to what I been experiencing exactly as you described. Yes I got flashing check Engine light that it flashes just as you showed in the video.... what was the fix for everything you talked about here ?
I got an 07 ford f150 4.6l and replaced the trans with a rebuilt from Monsterand some where between 1st into 2nd jerks a little but no codes truck rides fine from 2nd through 4th so I'm kinda unsure.
I have a 07 mkx when im cruising about 40 mph the revs are about 1100 to 1200 rpm if i give it light throttle it will stutter hard feels like its cutting in and out for a few seconds and then downshifts and is fine... transmission isnt slipping and no other issues would that be a possible misfire or does that sound like transmission problems
Hi, what cylinder exactly? My car, camry 2016 stalls between RPM 40-70 while slowly accelerated. In quick start it doesnt stall at all? Is it ignition coil or...? Appreciate your assistance
We have this exact problem on our 2008 Edge but I am unsure which Cylinder. I live 38 miles from the closest Ford Dealer and getting the vehicle from my wife during business hours is difficult. When you pulled the #4 Coil, could you see any arching or visible malfunction? We are at 95k so it's time for plugs anyway, I was hoping to see evidence on either the plug or coil of which cylinder it is. It's gotten more frequent so I would think the plug may show signs of more carbon build up on the cylinder dropping out? I see your RC Car and boat vids, that's awesome. I am the Southeast Area Administrator for Team Associated. Common connection there.
My 2000 f150 4.6 does this hard jerking and also dies when I come to a stop but only when I use my air and defrost. Is their a fix. I've changed all coils and that don't fix it.
Have you ever experienced a Ford shutting down a whole side of coil over plugs ? I have a v10 that has shut down 6 thru 10 cylinders. Any help would be appreciated.....
Hola my check engine light has come on a few times over the past couple of months with a p0302 code. I could feel an intermittent slight miss at idle for a month then the trans started slipping but the missfire has decreased in frequency I think I had 16 this morning on my 7 minute drive to work not that many. And they are very slight. Could that cause the feeling of a slipping trans or is that a separate issue? It's significantly worse on a cold start
Is there a way i can talk to you on a phone and ask questions about my problem with my 2001 lincoln navigator I had a check engine light on for a misfire in cylinder 4 code was PO4 I GOT IT FIXED IT WENT AWAY THEN TWO WEEKS LATER CAME BACK .... SO AFTER THAT I CHANGED ALL THE CYLINDERS ON THE LEFT SIDE AFTER THAT THE LIGHT LEFT HAD NO MISFIRE NEVER HAD A SHAKING ISSUE JUST AT ONE POINT I FELT A SMALL JERK WHEN I WOULD PULL OFF ... SO 4 MONTHS LATER I START HAVING A OVER HEATING PROBLEM TOOK IT TO SHOP I NEEDED NEW WARTER PUMP GOT THAT DONE I WAS ROLLING NO ISSUES DRIVING EVERYWERE I NOTICE THAT WHEN I WOULD COAST IN APARTMENT COMPLEX OVER SPPED BUMPS ID FEEL A THUD SOUND FROM UNDERNEATH SUV I WAS TOLD IT WAS A HARD SHIFT BEACUSE O HAVE A LARGE TRANSMISSION SO NOW MONTHS LATER IM UNABLE TO DRIVE FOWARD BUT REVERSE WORKS WELL AND THATS WERE I AM TODAY I WAS TOLD I COULD HAVE A GASKET ISSUE AS WELL BECAUSE I DIDNT START UP SUV IN WEEK AND WHITE THICK SMOKE HAD STARTED TO COME OUT RHE TAIL PIPE THEN AFTER WARM UP IT WOULD THIN UP AND THEN G AWAY .. I HAVE NO MILKY NESS IN OIL AND I WAS TOLD IT COULD BE A TRANSMISSION SELINOED ISSUE AND IM JUST EXHAUSTED I CANT AFFORD A NEW AUTOMOBILE RIGHT NOW AND I HOPE I DONT GET OVER PRICED FOR WORK BECAUSE IT WIL BE HARD TO COME UP WITH A REASON MY LIFE IS SUCKING AT THIS POINT.
I have a strange bucking when going from a stop if i sort of floor it the whole truck bucks like a hard shift, but if i go slow i dont really notice it, afraid it could be the trans but not sure..
This is exactly what my Mercury Mariner does and it has been to 2 Ford dealerships and several independent mechanics that can't seem to diagnose it. It is pretty much a new car with everything they have replaced on it (that hasn't helped).
2007 5.4 F150 I just had this exact thing happen to me two weeks ago before I saw this video. Thought my transmission was going out. Next day it threw a code, misfire on cylinder 7. Changed the plug and 1,000 miles later all seems to be well.
I have a 99 Lincoln Town car. My car does this and I've changed the spark plugs and the coils twice! I've heard it could be a wiring problem.... What do you think?
It's exactly what my Altima was doing. I thought it was a trans issue. The symptoms were exact. Turns out my spark plugs were extremely worn. Listen to him. He's on point.
Very nice video! Thank you wizard. I have a question, I have a 92 Mercury Topaz 3.0, when I first start the car it starts ok and idles "fine" for 20 seconds, then starts misfiring, (If I drive it at that moment it feels heavy), if I'm in park and give it gas it helps it to stabilize but when releasing the pedal it goes back to misfiring. After it warms up the misfire goes away 89%, it feels better and has more power. The misfires aren't constant, sometimes when I'm in a stop sign car almost wants to stall for a sec, however, it's not that common. I came into conclusion it's a spark issue since fuel pressure is perfect even when it misfires, all injectors are clicking also. What could the issue be? It's OBD1 I can't use my scanner to diagnose it better and it has no codes related to that on the self-test (KOEO and KOER). When clear flood cranking engine sounds even, so I assume it's not compression. OH BTW tailpipe smells awful, not like a rich condition, it's a different very strong smell and produces headaches; also I rebuilt the engine because it overheated but the problem was kind of there before. Please help!!! :(
@@farajalagory8027 hi! Actually I didn’t get to fix it yet. I moved away shortly after that comment and parked the car since, hope I can soon sort everything out again. What I do remember actually is diagnosing a couple of weeks before parking, is a bad bank 2 S1 O2 sensor. That sensor began to fail completely and not report right and was flooding that bank with fuel even in hot. That makes sense to be the culprit of those cold misfires because before it completely failed, for the first 20 seconds that was fine with no misfire I assume it was still in open loop so the O2s don’t read. After those 20 seconds the sensors start reading and as that sensor was in the verge of dying it threw the correct mixture away until it got hot enough.
I have a 2008 F150 4.2 L V6 61000 miles w/ knock on hills; Can I use Premium fuel. The manual says never to use premium if any problem go to another brand. I use quality fuel usually BP. Will using premium fuel do any damages?????
I have a 98 ford ranger 4.0 that stutters misfires and hesitating under low rpm load or right after up shifts and low power and bad fuel economy what could it be ?
Ufff maybe this could be..get two trans mechanic scanned both and no issue found and drive normally no issue..so one showme that scanner says cilunder 4 misfire...can i test it with forscan? Or what tool do yo use?? Only get chech engine p0420 and p2196..could this affect too? Thanks
my red 1998 for f150 does this right when I hit about the 20 mph mark my truck feels like it just jerks forward I switched out the transmission but it still does this and sometimes I don't know how to say but if it is a misfire It feels like it just t keeps misfiring like at first it misfires then it just keep s misfiring misfiring and misfiring it does it sometimes not all the times do
I have something that seems similar to this. I have a 2006 Pontiac grand prix that occasionally dies immediately after its started. It's also sometimes pretty rough to start. I've also noticed this "jerking" that he referred to in the video, only it happens when my car is upshifting. I'm worried it may be the transmission but after watching this I'm hoping its not
I have a 2005 grand prix with a weird shifting issue. It revs a few times rather than shift into 2nd and 3rd then eventually shifts 4th. Then it goes into this weird mode where the engine noise changes and it makes a surging noise from 1st into 2nd gear and shifts hard then shifts hard and weird in 3rd and 4th gear. It doesn't rev in this "mode" it actually shifts rather than rev but shifts hard and weird every gear. When I turn off car and turn it on after 30 seconds this mode goes away. Only right when i drive the car for the 1st time for the day it shifts normal for a couple min. Does everybody know what this is? There is no check engine light on either.
GREAT video! I have a 2009 Sable with 3.5 and I have similar issue...NO engine light. Hard shift (seemingly) when light throttle, vehicle will have a jerk to it then I will accelerate a little bit and goes away, but if I ease of throttle , vehicle will do same thing until I give more throttle or let up off throttle. Somedays no problem at all. What your think?
I have a 2005 Ford Escape doing the same thing once I hit over 45-50mph. I’ll change 4,5,6 spark plug and coil boots. Can’t do 1,2,3 because there under the manifold. Hopefully one of them solves the problem.... thanks for the info
I own a Ford Fusion 2015 SE 2.0 ECOBOOST engine that’s FWD. My car has done 54K KMS and since 20K KMS I’ve been having issues with my transmission and facing the following concerns 1. At lowers gears, the shifts are slightly delayed, harsh and lurches the car forward if the gear shifts at lower acceleration and speeds especially during traffic situations 2. When I bring the car to a complete stop, the car produces a knocking sound and lurches forward at the last reverse gear shift 3. I feel the 3rd reverse gear shift to be harder and harsh compared to others 4. When I accelerate from zero, there is a knocking sound as well. I’ve been complaining about this to Ford since 20K KMS and they have been coming back stating this is normal in this car, but I don’t think so as this is not normal characteristic of any car. At 30K KMS I went ahead and escalated the issue to the service manager who then observed this characteristic of the car and then decided to observe keeping the car for like 10 days and decided to change some solenoids along with some drive cycle was done with some software reprogramming. This did help to reduce the issue but I feel now it has come back making it really irritating to drive the car and I’m not satisfied I’ve gone back to the service manager and asked to give me a test drive on the same model so that I can confirm if this is a normal characteristic of this car. Which they said they will take a week and get back to me. do you feel this is an issue with my transmission? Have you come across such situations with cars, and what would you do ? Let me know ...
Ex-muslim Atheist Your transmission is probably going out or already bad. I had a 2003 Accord V6 and had the same issue. Both cars use the same engine and transmission.
My company has a bunch of f150 5.0 trucks 2019-2022 and ive been in 3 now that when you accelerate from the light consistently randomly it pops and backfires in the intake. Drops power like the timing is messed up. Just got mine back from ford replaced cam phasers and still have the problem. Any ideas? Any help is appreciated.
Did power balance on my supercharged 2015 Roush stage3. Cyl 2,3,5,and 8 was misfiring with no codes, changed plugs and coil packs, still have same misfires, I’m now thinking injector issues. What say you? The injectors are the LU47
I've got a 2010 FX Ford F-150 it's lifted with an exhaust, and it has a cylinder 8 slight misfire, I don't know how accurate that is because it runs fine, idles fine, sounds fine. I'm so confused.
Did you ever figure it out? My 2011 Towncar 4.6 had an engine coolant leak from the intake manifold and that would go right into the #8 spark plug well.
My wife's 2011 Nissan Rogue has this exact same condition going on. We thought her CVT transmission might be acting up but it only does it at certain times when you're giving it gas starting to go up a slight incline or sometimes just driving down the road. I thought it might be a misfire, but the engine light has not come on, and while watching the RPM gauge when this happens, I do not see the RPMs drop at all. It has been a while since I scanned it, so I'm going to get it scanned again to see if there are any new misfire codes. We replaced one factory coil that had went out with an O'Reilly coil and we thought it was doing okay. Now I'm wondering if that non-factory coil might have problems.
@@jasonfromm5637 I'm not running the after market coil anymore, and there are no misfires with OEM coils in. The transmission is still acting up the same way. I have resorted to pushing the button to lock out overdrive when I am driving under 35 miles per hour or so. This keeps it from jerking until I get up in speed, and then I depress the button again to accelerate up past 40.
Eric Hansen did it feel like it was slipping while at half throttle or so? my trucks fine when WOT or pussy footing it, but when i give it more gas but not quite enough to downshift it feels like slips but.. its odd 2013 f150 here.
I have a 2008 Ford Taurus X SEL with v6. I changed all the spark plugs. How does anyone know for SURE that there is no space or gap between COP inside plug area and the top part of the spark plug? How do we know or prove when you push a cop over a spark plug that it has snapped or clicked into place, it always feels rubbery. Lets say its on there but not snapped, does this cause an internal spark jump inside, and is that ok? Thank you... P.S. The plugs I put in are NGK and are 1/8" LONGER in that section where it would snap on cop internal.
my ‘93 mark viii 4.6 dohc feels like it’s got a trans problem at around 38-40mph...feels like torque converter slipping...jerks when i let off the gas. i get a check engine light occasionally too. now i wonder if its a misfire. i’ve got new plugs and wires...maybe i’ll replace my two coil packs and see what happens!
Same here on my 2000 F150. NOBODY seems to be addressing this issue. I've been told the transmission, torque converter, u-joints, coil packs, and now the spark plugs... after weeks and weeks of independent research, I have found that I have coolant leaking into my spark plug wells and have realized that this is a VERY common issue with the TRITON 4.6, 5.4, and 6.3 engines due to a faulty air intake design. I now need to order myself a quality intake system ($120-$400) and possibly even inspect my catalytic converter after driving around with this occasional issue for months now and no engine light. I am ranting, but am also mindlessly typing during this informative video. Part of this issue could be a faulty u-joint if the issue is just slight jolting and start and stopping with a slightly eratic humm while driving, but in my case - it is definitely a misfire. UPDATE: engine light came on, and I pulled into O'Reillys and had a P0300 code, which is multiple random misfires... time to change my plugs and diagnose the issue... I am by no means q professional and am just a mechanically inclined college kid who loves my truck more than I probably should.

And four years later I can still say the same thing. You're the lifeguard of poor Ford owners who are treading the cesspool of modern automotive engineering .
Thanks so much!
Mark 2007 Lincoln navigator, 5.4L 3v
07 Explorer, 40mph in OD plus a light load created violent jerk. Independent wanted to pull trans, rebuild/diagnose for $3000. Took to dealership was told #5 needs COP and plug. A few more of your videos about the dreaded 3V plug and less than $500 later runs perfect. Thanks for all the great videos!
thank you so much for this video. this is exactly what my ford expedition is experiencing. this saturday my mechanic will be changing the spark plugs and coils
FordTechMakuloco:
THANK YOU! THANK YOU! THANK YOU!
Thank you SO much for this video!
I was having a nearly IDENTICAL problem with my vehicle (Nissan Frontier). I had taken a long trip, and on the way home, my vehicle was doing the same exact thing, at the same speed range. I was agonizing over what might have been a nearly $6,000 repair/replacement for a transmission. Luckily, last night, I came across your video, so I watched the whole video. Today, I did use a scan tool, and, SURE ENOUGH, I found misfire events on one cylinder. I pulled the coil pack on that cylinder, and the coil pack assembly was broken. Since my vehicle is high mileage and 8 years old, I replaced all the coil pack assemblies. My vehicle runs great now!!! I spent $400 instead of potentially $6,000.
Again, THANK YOU!!!!
(I am going to share your video on TH-cam, hoping it can help some other people, too)
I have frontier 2014 and now it is jerking terribly. Do u think it is the same problem you had? Thanks
@@jacobadams8073 ...It is possible. The best way to find out is a scan tool. Another very quick way is to pull each coil pack and physically check each one for damage/excessive wear. This would eliminate or possibly confirm the jerking.
One last thing: check the cleanliness of your throttle body assembly AND your MAF sensor.
Good luck, but best bet is a scan tool.
@@dlopester13 thanks Diego ima give it a try. Thanks again.
Someone told me it could be my catalytic converter. But I asked my friend to check it out and he told me I need knew coils and spark plugs and it’s crazy because my check engine light was blinking like the video and would shut off after four blinks. Then went home and left to buy a code reader and it had 3 misfire codes 0300 0302 and 0304. It’s just crazy how my friend knew what potentially could be my problem for power loss and thanks to this video I have hope 🙏
Brian, Dude, you what makes the day after New Years Rock? Yup you got it... me re-watching your videos! Always Rocking!! Thx for all you do.
07 FX2 doing the same. $119 for the Diagnostic at Ford. Love your channel. Keep up the great work.
05 Ford F350 5.4 3v Truck was doing that and eventually was throwing code for cylinder 5 and 6 misfire p0300 p0305 p0306
Load on my scanner at idle was at 39% timing was reading from 15 to 45 rough idle and rough start up . Was shaking like crazy. Under load flashing light and goes away when you let go.
All plugs and coils checked out good no water or anything else in the holes. Left side cover off and it turned out to be #6 exhaust valve spring was broken.
Well while in there already did complete timing job and all following your instructions.
Couldn't have done this without you.
Your work is much appreciated.
Thank you
this was the video that i used to repair my issue same problem no mechanic was able to find the issue until i had an friend that had an ford IDS program and showed him this video and agree that cylinder 5 was causing the misfire .replaced the coils on all and spark plugs i have used pulse star. PROBLEM FIXED . THANK YOU!!!!!!!
Thank you very much...you save me a transmission job...had this same misfire since Christmas..jerking and slamming. And it was a dead mis...one coil.was totally dead..change all 4
THANK YOU VERY MUCH
My truck is Nissan pathfinder 2001 2WD has exact problem for months,i thought that is transmission problem,after watched your video last night i run to auto parts next day and get new set of sparkplug Bosch.wow,power gain and down shift seem like is gone,a very very slightly some time,now i just need clean MAP sensor and re-adjust throttle position sensor too.Thank you again.
Hey man. Thank you for uploading your videos. They are very helpful! You are awesome! Thx again!
And four years later I can still say the same thing. You're the lifeguard of poor Ford owners who are treading the cesspool of modern automotive engineering
I want to tell you thank you so much for this video it went out an back to Ford dealership.First trip did reflash ,on second trip it was throwing codes P0717 an U0100. .. they changed both sensors out picked vehicle up thinking its fixed.No still missing feeling like transmission slipping. .....hooked up to scanner no codes.Had them hook computer an drive it different story misfire on coil #1 an #4 .......so going to fix end of this week an replace all plugs. FORD FLEX 2009 lets hope this does it!!!!;)
Perfectly explained the issue I had with my 3.5 mkx. Took two Ford dealers to diagnose. Thankfully the second dealership had a thoughtful tech who took my vehicle home and drove it for awhile with the scanner on it and finally diagnosed it. Now I recognize it happening again. This time is a full on tune up.
Thanks very much.. I thought it was my transmission because I had gotten new engine mounts and I sometimes would feel that hard jerk on the engine... and the only codes that came on were fuel injection codes ....
The more you know
Dude I freakin love you. Thank you so much for all this info. You are most definitely the man. 👊🏻👍🏻👍🏻
Hi Makuloco I just got me a project 06 F-150 5.4 Triton V8. 77k miles and it misfires under load. The repair is straight forward (new spark plugs and ignition coils). If I want to advance my auto repair skills I need a scanner to learn how to diagnose like you did in this video. I was recommended the Autel MaxiAp200 and FORScan, but I rather get a recommendation from an actual Ford mechanic that has extensive knowlegde on the Triton V8. Thanks in advance!
Hi thanks for you video it stopped me from removing my transmission which i was about to start removing in an hour my 99 windstar started to shudder when light acceleration especially on hills or loaded van with the ac on and hard up/down shifts between 1st - 2nd especially when warmed up . I started to see these problems after my engine ceased on me due to the lower intake manifold gaskets leaked i figured it out after it ceased and started opening up the engine and found most of the water in cyl 2. to startup the engine I watched a youtube video where the guy sprays wd 40 into the cylinders and cranks the engine by hand and it worked for me but i didnt bore out or replace any piston rings currently i dont have any codes but my scanner does show a slight percent of cyl 2 misfire. it does seem the shudder gets a little better when i use thicker oil instead of 5w20. thinking the transmission was bad i added the lucas transmission fix into the transmission i dont have any shuddering or hard shifts now but it seems i dont have enough power when acceleration i was still in doubt that its the transmission or the TC, i also was in doubt that i shorted the tcc solenoid for some reason as my brake light switch wire had a loose connnection as i read a post saying that the brake switch has to do something with the tcc solenoid, but that doesnt seem the case now after watching your video now i think i will have to start digging into the engine check the cyl pressure etc.. but still i would ask you to recommend me where to start engine? or transmission? thanks
2009 ranger same harsh miss, only in overdrive going up a hill when the trans should downshift. Tested everything. This happened 1 year after changing spark plugs with NGK. Replace NGK with Motocraft, same issue. Finally replaced plug wires and problem solved, and I should have done this before changing the NGK spark plugs. NEVER had an issue with NGK on any vehicle or equipment I have used NGK spark plugs on. Even Ford with no codes couldn't find it, except that I should have the trans fluid changed. At $250 less tax I am glad I did my own testing. Hard miss as Brian has said in another video is usually seconday ignition. He was bang on with that.
Thanks so much for sharing your knowledge.
A lot of people don't know that the Alternator can also cause a car to jerk....I had this experience before.....what happens is, your car is losing power and if the alternator is bad or has bad voltage being sent between the battery and distributor cap, the power won't get sent properly to those other parts like the spark plugs which would misfire.
I've been experiencing jerks for about 8mo now, when accelerating between 25-35mph, and also while maintaining a speed of about 45mph.
No lights on the dash, and no codes thrown... until yesterday.
Check engine light came on, then battery light.
Got the battery tested, and they said my voltage regulator is faulty.
I've been wondering all day if the two are related?
@@muhammod95i wonder if thats why my car is doing it. my key fob just started being way more faulty too
Did the jerking go away after replacing the regulator?
I had that problem with my 93 mark VIII. I changed the alternator and it went away.
Good info. My 08 F-150 5.4 is doing this and I first thought it was trans.. It almost never fails, not through all rpms and gears but always at around 1200 RPM between 40-50 mph with any pull on the engine It starts jerking hard repeatedly. If I stab the gas and it pulls harder It still noticeably does it and the check light starts flashing just as it does here. Now to see if I can afford to have it checked out..
I know the feeling. Only mine does that only at idle, like at a stop light with the brakes on. Weird stumble jerk random.
Mine does same thing not when driving only at idle like at lights and it only happens sometimes
thanks for this video. My problem is the same, but i have a 5.4l and I believe it was never serviced while owned prior to me... it is sad how people take advantage of others.
Same last owner looked like he didn't do no service to it
I have a ford Ranger with a cylinder 4 misfire code and a shake and occasional jerk. I replaced the plug wire and coil pack. It seems to run better with no misses so far, but the dead miss is so intermittent it is hard to tell if that is the fix. Thanks for the video!
Says comment was 5 years ago , oops, did you feel the harsh shifts on up shifts too? my ford ranger is throwing the 4th cylinder missfire code too..
Let us know
For the past year I thought that this was a transmission. I’ve been saving to put in a new trans. Just to find out if was a misfire
Hey man, sometimes after driving for a little while 20mins or so when i put my foot on the acclerator, the exhaust sounds louder and discontinuous ( sounds like small explosions after each other). This sound goes straight away when I restart the engine strangely! could this be due to engine misfire or somethung else?
But as i said it doesn't always come on and goes away when i restart the engine!
any ideas or suggestion is much appreciated
ps i dont get any dashboard lights
Had this happen on my mom's '99 Mustang GT 4.6L 2v/auto trans. Felt like trans stutter between 3rd and 4th (40~45mph) during light acceleration. Checked trans fluid;ok. Had her take it to our her local Ford dealership and they told her it was a bad coil on cyl #1. Didn't make any sense to me since it only occurred as stated. In my way of thinking I figured I should have also felt it during WOT but didn't. But I went ahead and temporarily swapped in a spare known good coil from my '06 GT 4.6L GT (swapped the coil boots too). Noticed that there was dried out dielectric grease in the original boot and tip of coil spring and cleaned them up. Test drove it and no stuttering. Hmmm. Swapped the coils back just to be sure. Again no stuttering. Must have been poor contact between the tip of the spark plug and the coil tip (solid tip on spring). Though the tech was correct in diagnosing a misfire he was quick to say it was a failed coil which they wanted to charge $150 to replace.
My 2004 Acura TL did exactly what he was showing in the video. Cars parked at home right now friend of mine looked at codes and it was random misfire p0300 and said all he cylinders were misfiring. Gonna do a comparison test hoping it’s something little
I've been driving with bad ignition coils, and have had the symptoms you describe at the start. But those are actual downshifts, due to the lack of power in the engine.
me to
2007 Lincoln MKZ here ..Same here
Hard shift 1-2...changed shift accumulator, MAF sensor, VSS, transmission fluid and no luck. Havent changed TPS because i feel you have to recalibrate it. Ive also searched around and read spark plugs/wires cause mis-fire which is causing the hard shift 1-2.
I recently took my car to the shop with a misfire on #5 in a Cadillac DeVille DTS. Now they have took the ground wire routed to the #4 & 5. Now transmission switching horrible. I believe they burned out the ground wire.
I have a 2011 f350 6.7l. I need to replace the solenoids in the tranny and was wondering if you could let me know the best way to replace them.
Seen the video you replacing the tranny fluid and seen the solenoids and just wished you had a video on replacing them too.
YO! This is one of the best pieces of information on this so far!
This video helped me out a LOT! Thank you!!!
Aloha, love your channel and approach to difficult, hard to fix issues on Ford's. I have a1990 Econoline with a hard miss and shuddering. The van sits 6 months out of the year. recently I replaced the distributor, plugs, wires, coil. What are the odds that the ecu has leaking capacitors contributing to this?. Is this more difficult to diagnose on an OBD1 system. ? any input would be appreciated.
I have a 2005 Ford Freestyle. The symptom is that it shudders while driving and at times a it shuts off while driving, but not all the time. I noticed that the issue occurs when i filled the tank. Once it drops to half a tank it drives great. I have replaced (Throttled body, EGR, Computer, 1 coli for miss fire on cylinder 3, Fuel Filter, Fuel Pump) and still have the same symptom. On a Ford blog page. The Ford tech says that it is the Throddle body but still have the problem. Any idea on what it might be? I did get a new AC system for the car. It seemed that once i got a whole new AC system. This problem occurred after 2 month's after the AC system was installed.
my 05 mustang has been running poorly lately kinda similar to this. i get the flashing check engine light usually when i try to drive the car hard as in push it to red line and make it shift under power but instead it won't shift until i let off and will usually flash the check engine light. first i was thinking bad transmission but after seeing this I'm thinking maybe it really is a misfire that is my main issue. the car doesn't usually misfire under normal driving but i went out after watching this and did notice if i put my hand on the intake manifold i can feel an irregularity in the idle like a small misfire is going on. going to check plugs and wires in the morning and compression test and go from there.
hey i got a question for you! i have a 2015 ford escape 2.0 EcoBoost with 122k. recently when i first start my car and i usually let it idle for about 3 minutes and i put it in drive and the car jolts a little bit! if i put it in reverse or neutral its all smooth! once the car warms up everything is smooth like coming out of a store start the car put it in drive and its smooth only when i first start my car, my transmission was rebuilt at 53k and now has 122k on it, last week i did do a transmission drain and fill on it and the transmission fluid was dirty and black! but it did have a little red color to it! and the transmission fluid didnt smell burnt. it seemed to fix the problem start the car in the morning put it in drive all smooth! i think the problem is coming back when i put the car in drive its very slight jerk, do you think i should do another drain and fill on the transmission to get more of the dirty fluid out? any advice? oh yeah no check engine light on.
I have cylinder 4 & 2 misfire with map sensor code and shuddering at 40 m.p.h. in 3rd or overdrive. In 2nd it will misfire but wont shudder. What do u think? Thanks for advice. Its a 2005 ford escape with 3.0. Engine light is on.
I have a 2008 Mercury Mountaineer V6 4.0L and I am having a random misfire issue on cyl 5 as well as "hard shifting" on 2nd and 3rd gear. I'm not sure if they are the same issue or separate. Neither issue is every time. Recent maintenance I've done includes water pump, harmonic balancer, belt, plugs, and leads. The misfire seems like it could be the EGR? I am getting both negative and postive readings on my EGR_ERR, telling me it isn't always moving the amount the computer is calling for. Maybe I'm going down the wrong path... Any ideas? Also, trying to figure out if my hard shifting is a misfire or not. My misfire will go away after shutting down the vehicle and restarting it. Could it be a sensor? Thats is what I am leaning towards...
Ford Ranger 2014 model 2.2l 4x2 (manual tranny, turbo).
The problem is, when at 2nd gear or 3rd gear and accelerating from a running stage or climbing it's power is so weak, if rpm is below 1500 it doesn't have power on it, it just slowly picking up and picking up power even if it's already floored. It's so weak it feels like stalling if you have not enough propulsion goin up or if the car you are following suddenly drops speed then you have to change to the lower gears immediately or press clutch then rev it or else you will stall. But then, when rpm finally gets past 2k, it will suddenly picks up power like a a multiple vtec-like power just kicks in. The power delivery is not smooth. Slow acceleration then only picks up power at certain rpm.
I replaced all filters already (Fuel filter, Engine Air intake filter) I also changed oil on engine, transmission and even the rear axles with all-AMSOIL fluids. I also asked a friend to clean the EGR. I also replaced the turbo hose in the top. I also added an TECHRON Diesel additive in my last fuel fill to clean injector and fuel lines. Yes I feel a little bit of improvement after all of these cleaning and stuff, but the uneven power delivery and poor low rpm power is still there, it's still bothering me.
It's not like that before, I tried two trucks of the same model and specs from a group and they does not act like they were smooth and torqy. It's not normal.
What should I check? Shall I clean the exhaust? Catalytic, does it have catalytic or something? At higher speeds no problem, it's a fast truck when it's already at speed.
One thing I am noticing is when accelerating the sound also has a tractor-like sound effect if it's accelerating and the tractor sound effect goes away when it gets to speed already. But pressing gas and revving when parked does not create that sound. the sound only appears when accelerating.
shifting is also not smooth, there is a jerk when shifting to other gears.. harsher on downshift. No matter how good rev match I do, it still not smooth transition of gears. No check engines in the Ford Ranger.
Got a 2002 ford super crew 5.4 triton. Hit a big bump and it either dies or the instrument panel ac and all goes dead then comes back on. Any ideas what i got going on.
I'm a tech also and love you videos keep them coming
Will do!
@@FordTechMakuloco what's the name of that software u used to diagnostic the misfire????
@@FordTechMakulocoI have a 13 eco boost. That misfire when hard acceleration changed plug and coils. Same issue. Misfire changes all over
I recently bought a 04 freestar and it has been trouble since day one the only code that comes up is the coil pack so 3 coil packs and new plugs and wires later it still idles rough bogs down and has no power I tried to go uphill in it the rpms were at 3000 and it was barely going 15mph I'm at a loss I just don't what else it could be
got a 96 2.3 ranger. 5 speed. everytime I hit a bump it sort of bucks. it wants to die whenever it happens. I push the clutch in, and it's fine going over bumps. any ideas?
I have a 2003 Toyota solara. When I drive and am coasting my RPM’s will fluctuate and it feels like my transmission is downshifting hard. Literally feels like a jump. Do you think this could be the cause? Thanks.
This is so helpful! Thank you very much
I have 2005 f250 with the 5.4 3 valve. I replaced all the coils. I pull a trailer with it (5500 lbs) and while accelerating at high rpms it hesitates and shudders a little or no power. I was thinking I may have a fuel issue or injector issue? 200,000 miles, Just turned over this weekend.
Mine has the same issue. I just got a melling oil pump on it and new phasers and now it has a cylinder number 4 misfire
I have and 04 f150 it does the same thing wid did u do to fix the problem ?
Hey in my 08 Tundra 5.7liter the truck at 30mph to 40mph when I coast and let off the acceralater the truck downshift pretty fast and I have to give it more gas to keep going is that normal
I get zero lights. Ive got the 4.0, 03 explorer. It has violent bang when going up a hill or on a pull? Ive had the drive line looked at. Full compression on all cylinders. No lights at all. We did new bearings and hubs and the transfer case seems good. Rear gears seems good no metal. Its got 169k miles. Ive had it at an independent shop with no success but have an appointment next week for at the Ford service. Any help would be greatly appreciated.
2015 ford focus doing the exact same thing, any tips?
I have a problem like this in 2004 5.4 3v F150. Its the no codes thing that is confusing local shop. I will be driving along and all the sudden truck feels like it hits dead spot then runs like nothing happened. Changed coils and engine feels stronger but still does this. Again no codes. What should I tell them to look for?
My 2003 ford focus is sounding like a hell cat when i accelerate past 20mph dont know whats wrong any help please
I have a 2008 f150. The truck is confusing me. When I am going down the road in first and second gear I am fine but when it shifts into third and rpm is up to 1500 it starts jerking and while truck is shaking/vibrating. I rev up to 2000 rpm and it stops. The only thing I can think of is that there is a possible warped rotor or something wrong with the drivetrain. Any thoughts?
HELP PLEASE!!!! I changed the coil and spark plug on my F150 2000 4.6l
but still get a misfire code. I forgot to blow the chamber out though, no oil found but could it be dirty????? Thanks
Does this happen with a 2014 Taurus SHO?
2009 Flex. I changed the plugs and coil packs 5 months ago and everything was running great. Until now. It feels like 2 cylinders are cutting out. What could cause them to go bad so quickly?
Plugs backing out?
My wife 2007 Edge Sel awd 3.5L v6 suv has tow package & I think sport as well...(I think), Amy way just got Code P0303 cylinder 3 misfire. An the s7v does jerk at times so I am wondering if what you speaking upon here applies to what I been experiencing exactly as you described. Yes I got flashing check Engine light that it flashes just as you showed in the video.... what was the fix for everything you talked about here ?
Hey I just got my car out the shop yesterday and my 0/d light keep flashing on and off what's goin on?
I got an 07 ford f150 4.6l and replaced the trans with a rebuilt from Monsterand some where between 1st into 2nd jerks a little but no codes truck rides fine from 2nd through 4th so I'm kinda unsure.
exactly its happening here. thanks mate. i was thinking its transmission.
What was the problem how it got fixed
I have a 07 mkx when im cruising about 40 mph the revs are about 1100 to 1200 rpm if i give it light throttle it will stutter hard feels like its cutting in and out for a few seconds and then downshifts and is fine... transmission isnt slipping and no other issues would that be a possible misfire or does that sound like transmission problems
Hi, what cylinder exactly? My car, camry 2016 stalls between RPM 40-70 while slowly accelerated. In quick start it doesnt stall at all? Is it ignition coil or...? Appreciate your assistance
We have this exact problem on our 2008 Edge but I am unsure which Cylinder. I live 38 miles from the closest Ford Dealer and getting the vehicle from my wife during business hours is difficult. When you pulled the #4 Coil, could you see any arching or visible malfunction? We are at 95k so it's time for plugs anyway, I was hoping to see evidence on either the plug or coil of which cylinder it is. It's gotten more frequent so I would think the plug may show signs of more carbon build up on the cylinder dropping out? I see your RC Car and boat vids, that's awesome. I am the Southeast Area Administrator for Team Associated. Common connection there.
07 Nissan Altima does that jerking/hesitating like a down shift. No codes so spark plugs and wires should be checked first? Thanks ahead of time
Do you see this complain on 09 ford flex?? Good video bro thanks
My 2000 f150 4.6 does this hard jerking and also dies when I come to a stop but only when I use my air and defrost. Is their a fix. I've changed all coils and that don't fix it.
Have you ever experienced a Ford shutting down a whole side of coil over plugs ? I have a v10 that has shut down 6 thru 10 cylinders. Any help would be appreciated.....
Hola my check engine light has come on a few times over the past couple of months with a p0302 code. I could feel an intermittent slight miss at idle for a month then the trans started slipping but the missfire has decreased in frequency I think I had 16 this morning on my 7 minute drive to work not that many. And they are very slight. Could that cause the feeling of a slipping trans or is that a separate issue? It's significantly worse on a cold start
Is there a way i can talk to you on a phone and ask questions about my problem with my 2001 lincoln navigator I had a check engine light on for a misfire in cylinder 4 code was PO4 I GOT IT FIXED IT WENT AWAY THEN TWO WEEKS LATER CAME BACK .... SO AFTER THAT I CHANGED ALL THE CYLINDERS ON THE LEFT SIDE AFTER THAT THE LIGHT LEFT HAD NO MISFIRE NEVER HAD A SHAKING ISSUE JUST AT ONE POINT I FELT A SMALL JERK WHEN I WOULD PULL OFF ... SO 4 MONTHS LATER I START HAVING A OVER HEATING PROBLEM TOOK IT TO SHOP I NEEDED NEW WARTER PUMP GOT THAT DONE I WAS ROLLING NO ISSUES DRIVING EVERYWERE I NOTICE THAT WHEN I WOULD COAST IN APARTMENT COMPLEX OVER SPPED BUMPS ID FEEL A THUD SOUND FROM UNDERNEATH SUV I WAS TOLD IT WAS A HARD SHIFT BEACUSE O HAVE A LARGE TRANSMISSION SO NOW MONTHS LATER IM UNABLE TO DRIVE FOWARD BUT REVERSE WORKS WELL AND THATS WERE I AM TODAY I WAS TOLD I COULD HAVE A GASKET ISSUE AS WELL BECAUSE I DIDNT START UP SUV IN WEEK AND WHITE THICK SMOKE HAD STARTED TO COME OUT RHE TAIL PIPE THEN AFTER WARM UP IT WOULD THIN UP AND THEN G AWAY ..

I have a strange bucking when going from a stop if i sort of floor it the whole truck bucks like a hard shift, but if i go slow i dont really notice it, afraid it could be the trans but not sure..
This is exactly what my Mercury Mariner does and it has been to 2 Ford dealerships and several independent mechanics that can't seem to diagnose it. It is pretty much a new car with everything they have replaced on it (that hasn't helped).
2007 5.4 F150 I just had this exact thing happen to me two weeks ago before I saw this video. Thought my transmission was going out. Next day it threw a code, misfire on cylinder 7. Changed the plug and 1,000 miles later all seems to be well.
Did you only the spark plug? Or you also changed the coil as well?
I have a 99 Lincoln Town car. My car does this and I've changed the spark plugs and the coils twice! I've heard it could be a wiring problem.... What do you think?
It's exactly what my Altima was doing. I thought it was a trans issue. The symptoms were exact. Turns out my spark plugs were extremely worn. Listen to him. He's on point.
How many miles buddy?
Very nice video! Thank you wizard. I have a question, I have a 92 Mercury Topaz 3.0, when I first start the car it starts ok and idles "fine" for 20 seconds, then starts misfiring, (If I drive it at that moment it feels heavy), if I'm in park and give it gas it helps it to stabilize but when releasing the pedal it goes back to misfiring. After it warms up the misfire goes away 89%, it feels better and has more power. The misfires aren't constant, sometimes when I'm in a stop sign car almost wants to stall for a sec, however, it's not that common. I came into conclusion it's a spark issue since fuel pressure is perfect even when it misfires, all injectors are clicking also. What could the issue be? It's OBD1 I can't use my scanner to diagnose it better and it has no codes related to that on the self-test (KOEO and KOER). When clear flood cranking engine sounds even, so I assume it's not compression. OH BTW tailpipe smells awful, not like a rich condition, it's a different very strong smell and produces headaches; also I rebuilt the engine because it overheated but the problem was kind of there before. Please help!!! :(
Did you fix it?
@@farajalagory8027 hi! Actually I didn’t get to fix it yet. I moved away shortly after that comment and parked the car since, hope I can soon sort everything out again.
What I do remember actually is diagnosing a couple of weeks before parking, is a bad bank 2 S1 O2 sensor. That sensor began to fail completely and not report right and was flooding that bank with fuel even in hot.
That makes sense to be the culprit of those cold misfires because before it completely failed, for the first 20 seconds that was fine with no misfire I assume it was still in open loop so the O2s don’t read. After those 20 seconds the sensors start reading and as that sensor was in the verge of dying it threw the correct mixture away until it got hot enough.
I have a 2008 F150 4.2 L V6 61000 miles w/ knock on hills; Can I use Premium fuel. The manual says never to use premium if any problem go to another brand. I use quality fuel usually BP. Will using premium fuel do any damages?????
I have a 98 ford ranger 4.0 that stutters misfires and hesitating under low rpm load or right after up shifts and low power and bad fuel economy what could it be ?
Same, 4.0 sohc 2006.
Done Plugs, leads, fuel filter etc etc and is manual
Ufff maybe this could be..get two trans mechanic scanned both and no issue found and drive normally no issue..so one showme that scanner says cilunder 4 misfire...can i test it with forscan? Or what tool do yo use??
Only get chech engine p0420 and p2196..could this affect too? Thanks
my red 1998 for f150 does this right when I hit about the 20 mph mark my truck feels like it just jerks forward I switched out the transmission but it still does this and sometimes I don't know how to say but if it is a misfire It feels like it just t keeps misfiring like at first it misfires then it just keep s misfiring misfiring and misfiring it does it sometimes not all the times do
I have something that seems similar to this. I have a 2006 Pontiac grand prix that occasionally dies immediately after its started. It's also sometimes pretty rough to start. I've also noticed this "jerking" that he referred to in the video, only it happens when my car is upshifting. I'm worried it may be the transmission but after watching this I'm hoping its not
I have a 2005 grand prix with a weird shifting issue. It revs a few times rather than shift into 2nd and 3rd then eventually shifts 4th. Then it goes into this weird mode where the engine noise changes and it makes a surging noise from 1st into 2nd gear and shifts hard then shifts hard and weird in 3rd and 4th gear. It doesn't rev in this "mode" it actually shifts rather than rev but shifts hard and weird every gear. When I turn off car and turn it on after 30 seconds this mode goes away. Only right when i drive the car for the 1st time for the day it shifts normal for a couple min. Does everybody know what this is? There is no check engine light on either.
same car !!
i need to know too.
Spark plugs
GREAT video! I have a 2009 Sable with 3.5 and I have similar issue...NO engine light. Hard shift (seemingly) when light throttle, vehicle will have a jerk to it then I will accelerate a little bit and goes away, but if I ease of throttle , vehicle will do same thing until I give more throttle or let up off throttle. Somedays no problem at all.
What your think?
Am having the same problem
I have a 2005 Ford Escape doing the same thing once I hit over 45-50mph. I’ll change 4,5,6 spark plug and coil boots. Can’t do 1,2,3 because there under the manifold. Hopefully one of them solves the problem.... thanks for the info
Did that fix the problem ?
would it shudder if torque converter is bad if its in park
I own a Ford Fusion 2015 SE 2.0 ECOBOOST engine that’s FWD. My car has done 54K KMS and since 20K KMS I’ve been having issues with my transmission and facing the following concerns
1. At lowers gears, the shifts are slightly delayed, harsh and lurches the car forward if the gear shifts at lower acceleration and speeds especially during traffic situations
2. When I bring the car to a complete stop, the car produces a knocking sound and lurches forward at the last reverse gear shift
3. I feel the 3rd reverse gear shift to be harder and harsh compared to others
4. When I accelerate from zero, there is a knocking sound as well.
I’ve been complaining about this to Ford since 20K KMS and they have been coming back stating this is normal in this car, but I don’t think so as this is not normal characteristic of any car.
At 30K KMS I went ahead and escalated the issue to the service manager who then observed this characteristic of the car and then decided to observe keeping the car for like 10 days and decided to change some solenoids along with some drive cycle was done with some software reprogramming. This did help to reduce the issue but I feel now it has come back making it really irritating to drive the car and I’m not satisfied
I’ve gone back to the service manager and asked to give me a test drive on the same model so that I can confirm if this is a normal characteristic of this car. Which they said they will take a week and get back to me.
do you feel this is an issue with my transmission? Have you come across such situations with cars, and what would you do ?
Let me know ...
Hey. Did you find a fix for that? I'm having same issues with my Ford Mustang.
I have a Nissan but it's giving me the same issues. Lurch and jerking forward when accelerating and my gearshift sticks when I place it in park
Chevy traverse 2k11 having same issue sir, advise me what to do n how to fix it
Any idea.. ?😭 2003 Acura TL type s ..After I change spark plugs and coil - symptom now is rough shifting and lack of engine power during acceleration.
Ex-muslim Atheist Your transmission is probably going out or already bad. I had a 2003 Accord V6 and had the same issue. Both cars use the same engine and transmission.
My company has a bunch of f150 5.0 trucks 2019-2022 and ive been in 3 now that when you accelerate from the light consistently randomly it pops and backfires in the intake. Drops power like the timing is messed up. Just got mine back from ford replaced cam phasers and still have the problem. Any ideas? Any help is appreciated.
Another great video.
That is exactly what is happening in my honda. Finally figured it out. Thanks from my heart.
What fixed it? Mine is doing same thing
Did power balance on my supercharged 2015 Roush stage3. Cyl 2,3,5,and 8 was misfiring with no codes, changed plugs and coil packs, still have same misfires, I’m now thinking injector issues. What say you? The injectors are the LU47
I've got a 2010 FX Ford F-150 it's lifted with an exhaust, and it has a cylinder 8 slight misfire, I don't know how accurate that is because it runs fine, idles fine, sounds fine. I'm so confused.
Did you ever figure it out? My 2011 Towncar 4.6 had an engine coolant leak from the intake manifold and that would go right into the #8 spark plug well.
My wife's 2011 Nissan Rogue has this exact same condition going on. We thought her CVT transmission might be acting up but it only does it at certain times when you're giving it gas starting to go up a slight incline or sometimes just driving down the road. I thought it might be a misfire, but the engine light has not come on, and while watching the RPM gauge when this happens, I do not see the RPMs drop at all. It has been a while since I scanned it, so I'm going to get it scanned again to see if there are any new misfire codes. We replaced one factory coil that had went out with an O'Reilly coil and we thought it was doing okay. Now I'm wondering if that non-factory coil might have problems.
How’d that work out buddy?
@@jasonfromm5637 I'm not running the after market coil anymore, and there are no misfires with OEM coils in. The transmission is still acting up the same way. I have resorted to pushing the button to lock out overdrive when I am driving under 35 miles per hour or so. This keeps it from jerking until I get up in speed, and then I depress the button again to accelerate up past 40.
Am seeing this video in 2024 am so happy I had to subscribe 🎉
Right on. Thought I had a torque converter issue. Turned out to just be an old truck haha. Needed new engine coils and all that stuff
Eric Hansen did it feel like it was slipping while at half throttle or so? my trucks fine when WOT or pussy footing it, but when i give it more gas but not quite enough to downshift it feels like slips but.. its odd 2013 f150 here.
I have a 2008 Ford Taurus X SEL with v6. I changed all the spark plugs. How does anyone know for SURE that there is no space or gap between COP inside plug area and the top part of the spark plug? How do we know or prove when you push a cop over a spark plug that it has snapped or clicked into place, it always feels rubbery. Lets say its on there but not snapped, does this cause an internal spark jump inside, and is that ok? Thank you... P.S. The plugs I put in are NGK and are 1/8" LONGER in that section where it would snap on cop internal.
The coils do not snap onto the plugs they simply push against them with a long spring inside keeping the tension.
Hey, thank you so much, I appreciate it...
@@FordTechMakuloco I was wondering this very thing today when I replaced the plugs on my 3.5l explorer XLT. Thanks for the question AND answer
my ‘93 mark viii 4.6 dohc feels like it’s got a trans problem at around 38-40mph...feels like torque converter slipping...jerks when i let off the gas. i get a check engine light occasionally too. now i wonder if its a misfire. i’ve got new plugs and wires...maybe i’ll replace my two coil packs and see what happens!
Same here on my 2000 F150. NOBODY seems to be addressing this issue. I've been told the transmission, torque converter, u-joints, coil packs, and now the spark plugs... after weeks and weeks of independent research, I have found that I have coolant leaking into my spark plug wells and have realized that this is a VERY common issue with the TRITON 4.6, 5.4, and 6.3 engines due to a faulty air intake design.
I now need to order myself a quality intake system ($120-$400) and possibly even inspect my catalytic converter after driving around with this occasional issue for months now and no engine light. I am ranting, but am also mindlessly typing during this informative video.
Part of this issue could be a faulty u-joint if the issue is just slight jolting and start and stopping with a slightly eratic humm while driving, but in my case - it is definitely a misfire.
UPDATE: engine light came on, and I pulled into O'Reillys and had a P0300 code, which is multiple random misfires... time to change my plugs and diagnose the issue... I am by no means q professional and am just a mechanically inclined college kid who loves my truck more than I probably should.
