Is it bed too use anti seize on spark plugs??
Wish you were in my area. Your videos make owning a Ford an economical reality. Thanks again 🚘
Forscan is a great tool. Like it better on the laptop then the mobile app.
Yeah I paid almost double that then discovered they sold me iridium's. I had heard that turbo engines go through plugs faster than normally aspirated and needed changing more often.
Are those Motorcraft coils just rebranded Denso coils which are about 10 dollars cheaper?
Just had cylinder 1 go dead on my 2015 3.5 with 170k miles after letting the truck sit a while and filling the tank up. Was on highway 1-2 later and the violent shake happened. Flashing engine light just like you showed. Figured it was a valve spring breaking or something. I put msd coils in over 100k miles ago lord I hope that’s the issue. Never thought to swap ‘em around like you did. Gonna try that this weekend. Thanks for your continued videos, I’ve used quite a few over the years I’ve had my truck. Best Ford channel, no bs, just facts and experience from you.
Hey any updates ? I have the same issue. Thanks
[[[[
@@tommydodds sorry bud I never saw this. It was my injectors. Injectors were stuck open and caused all kinds of havoc. The high tune and close plugs made it hard to figure because at high rpm the truck would bark off all six.
Don’t let your ecoboost sit like I did! I thought I was doing it a favor getting a daily but nope.
This guy is great I don't even own a Ford vehicle anymore but I have continued to watch his videos and have been a long time subscriber only because I admire the knowledge that this guy has I am learning a lot about behaviours with vehicles and functions his narration and explanations about issues are probably the best I have seen on youtube and online Thank You so much for continuing to share your knowledge about issues and problems with vehicles and will always be looking forward to your next challenge you are a fine vehicle technician.
I know this is a year old and you probably won't get this msg, but THANKS Bunches !!! I have this problem too on my 2013 3.5 EcoBoost. What I lappreciate most about this video is that fact that you SHOWED us how to use Forscan. I got Forscan about a year ago and have used it several times, but not to this depth of trouble shooting my truck. Your step by step through the software REALLY helped !!! Keep up the great video and work for us !!! HUGE HELP !!!
but he's not even using forscan hes using IDS
hell yeah dude, I just bought a 2011 Ford F150 with the 3.5 Ecoboost and I'm following all your vids to redo it 300k miles
Wow, just got my morning coffee and saw this pop up. I have a 2012 blue flame super crew 3.5 EcoBoost. It has almost 121,000 and I'm always on the lookout for videos on this year and model. Good find!
Probably because it was a new revision and the old plugs proved to be a good design. When something works and people feel the need to change it you sometimes have to ask why.
I learned that lesson the hard way about the performance coils on the modern engines. I had previously worked on old Ford V8 stuff, so it was always a no brainer to go with an aftermarket coil and install electronic ignition in place of points. It always helped with performance and reliabilty. I put Accel coil packs on my '94 Saturn and had one go bad within a year. I saved the originals so I put them back on and it ran great until I sold the car years later. It seems the old days are gone when the aftermarket hot rod stuff works better than the OEM. All the manufacturers have really gotten their act together.
My father (A Master Mechanic) would say.
They spend millions of dollars designing and testing. And you intend to improve on that?
I can see this fellow going around and around chasing this problem never thinking his "NEW" coils could be at fault. Your diagnostic tool is awesome.
Had a p0304 on my 2015 Lincoln Navigator L and changed the spark plug on cylinder 4 using the guidance of this video. It was only $8 to fix this assuming the coil was not affected. Will change the other 5 plugs on my next day off. Saved me $300 and time wasted at the dealership!!! Thank you!!!
I’ve got a 2013 f150 ecoboost, I haven’t had any issues with it but you’ve definitely educated me on what to look out for. If I’m ever in your neck of the woods I’m buying you a beer.
You’re the man thank you for every video!
MSD STANDS FOR... MY SPARK DISAPPEARED .
Multiple Spark Discharge?
Motorcraft that came with my truck started missing at 80k. Put in a set of MSD and they started to miss at 150k.
Set of MSD in my mercury marauder has 100k and still going strong.
Your videos are extremely helpful beyond words. I bought a used 06 f150 with the 4.6. 70k miles yes i know low miles i was getting misfire on #3. Thanks to you i was able correctly diagnose the problem and prevent catastrophic damage . #3 plug was loose almost welded tip to electrode . Replaced coil in #3( looked like boot was burnt) and replaced all plugs. Discovered that 5 a bit loose as well but only 1/2 turn. Installed new plugs properly gapped with the nickel anti-sieze and torqued to 22 ft. lbs. Good to go . Thanks for all you do . I'm glad i didnt launch a plug that would have really sucked although i watched your vid on inserts and would have tackled it. 🙂
I can't express how much of a lifesaver your channel is! I have a 2012 F150 and was having issues going uphill and then putting the pedal down. Just recently the check engine light finally came on. I read the code and did a search on TH-cam and of course you pop up. I've been using your other videos to change out fluids and other maintenance. You're great at explaining things and very thorough.
UPDATE: Replaced plug and coil pack on cylinder 2. Still misfiring. I came across a TSB that says if you see carbon tracking on the plug, replace plugs and coil boots and should be good. I'm going to try and drain the intercooler as well
This it's beautiful vídeo I replaced the coil on cylinder #6 two times and do the semting, what you think?
I don't comment on videos often, but this video saved me some money. Luckily I have a scan tool that helped out as well. But the way you explain things and how you go through the process of elimination is outstanding. You have a subscriber for life here! The only thing I did different was move the coil pack in question to an easier location to remove so I don't have to remove the air intake and throttle body when I'm sure it's that coil pack. Great video! 👍
Thanks for the tips. I just purchased my 2014 F-150 3.5 ecoboost Nov. 2019 with 56,000 miles.
At 62,000 started feeling misfire. Replaced plugs and problem solved.
You are the man, great representation of diagnosing a misfire. These are crucial first steps that most people Ignore, as I have done this myself. New parts mean nothing.
The best F mechanic strikes again.
Yeah had the same Problem With my 5.4 Switch Out with a coil packs , Cylinder 2 Was Miss Firing Low and behold it was the spark plug and cylinder 2, Spark plug Was Misfiring So happy that I found that out.
Growing up in my fathers towing and repair shop he used to beat in my head .."Only use OEM Ford parts on Fords." and I have done it ever since..
I had a problem with my 07 Crown Vic PI, it went into limp mode, wrench icon. Turns out, it had an aftermarket air filter. I replaced it with a Ford filter, and problem solved.
Good advice... You have less issues months later.
Would you recomend the ngk spark plugs gapped right over ford brand ?
I had one original coil go out around 200k km while towing a couple years ago. Replaced with a napa one to get truck going right away. So far everything is good and ordered up a Ford spare and keep it in the truck just incase. Also keep a spare plug too because they go out every 80k km everytime.
Ford Co is finally smashing the Like button!
You the Man. Even though I drive a 2017 F250 6.2 gasser , I watch all your posts. Very informative for sure. Thanks for all the Videos .
Great video! Sometimes it's difficult to ignore new parts but this proves sticking to the basics works every time!!!
That’s the most frustrating thing when you diagnose a bad part so you replace it and then the new one doesn’t work either so you run around in circles for hours trying to diagnose another problem only to figure out your brand new part is just bad
What a crate video! I love learning from people who have a passion to do the right thing the right way with thoroughness right equipment etc. I really appreciate the example I’m trying to learn as much as I can about my truck in this video was very helpful.
Great video i had a tune up done and my sons truck ran fine afterwards, 2 months later it does the shaking worse!! I own a collision shop and have all the tools, scanners and things. Time i do not have so i assumed torque converter shudder. Picked it up last night still the same issues. I ran into this video before i trade this thing off came down to my shop ram the performance balance test and drive it!!! Cyl 1 and 2 for me half way done with inspection now! Sure wish i would’ve slotted time i would’ve saved some money 😂😂 th ask for the great video
Edit: 2 plugs cracked majorly Cyl 1&2
Thanks for this DIY video! Just got a’12 F150 EcoBoost 6cyl and P0303 came up. Cyl 3 has misfire. I got it back to firing correctly and think it was the coil. Much Grass Amigo!
Motorcraft parts for the win!
Back in the day, MSD was a pretty solid product. Accel was, too. Now both seem to have taken the 21st Century trend downward in quality, like so many once great brands have. No better example than this video right here!
Yeah them days are long gone...Everything made in China but they still charge the premium prices for the Name....
Thank you for this video .. By the way i am also a ford technician from the philippines .. It helped me a lot with your videos ..
I have a 4.6liter V8 on a Ford F150 210k miles. I made some maintenance parts changes changes which included the following:
Intake Manifold
Fuel injectors
PVC valve with new cover
Coils, spark plugs, VVT sensors, camshaft position sensors, didn't change phasers. After all those changes, initially it was running a little rough until eventually cleared up on its own. Checked codes and everything cleared up for about a month. This past Sunday, I decided to run the truck on third and second gear going up a mountain just to give those gears a workout on the transmission. Going downhill I put it back on drive and ended up eventually at a stop light and the truck started to vibrate like crazy. I could tell the timing was off, but as soon as I gave it gas, accelerated it stopped vibrating ran fine until my next full stop where it vibrated and died. Had a hard time turning it back on with several stallings. The odd thing was that no codes were given out by the computer the engine light never turned on but the oil spout icon did. I was eventually able to turn it on drive it home. Weirder thing is, got home and it was back to normal no more timing issues it has been several days now, and oil spout icon light turned off and it hasn't happened again. My guess is I have an oil pressure problem and maybe phasers are sticking, and/ or the oil pump needs replacement. Really need your opinion. What do you think? I would appreciate it your opinion.
By the way all ford parts. Except coils and denso spark plugs
4.6L doesn't use phasers or vvt.
@@DiscretesignalsPfaff! oh yes it does. Want the part numbers?
I have been let down by MSD coils. Fortunately I kept a OEM coil and a quick swap to the OEM Ford coil fixed the problem.
I have been without mine for over a year now I wish I had someone as smart as you in my town
Great video, Brian. I was considering MSD coils, as a performance upgrade for my 2015 Ecoboost Mustang. Not anymore! The stock Ford coils are working just fine and I won't have to spend $250 to create a new problem. Keep up the good work.
I put a set of MSD coils on my 5.0L and they failed in under 1 year. The place I bought it from gave me another set under warranty and 🤞 2 years later still good. I still have the OE coils just in case.
Love watching your tidbits about ford issues. I recently noticed a rough idle during startup from sitting a bit and wonder if I need to change out my plugs. It's a 2013 F150 3.5 Ecoboost. I just hit 50k miles.
Just had pretty much the exact same issue with my 2012 F150 3.5eco. Had check engine light/ sputtering while towing my trailer. Got a cylinder 4 misfire code. Did the coil swap check like shown in this vid. Swapped the suspect coil to cylinder 1 which then gave cylinder 1 misfire. We then got a aftermarket coil to replace it . That worked fine for all of ~500 miles towing before I got cylinder 1 misfire again. Brought it to Ford and they replaced it with a Ford coil. Also had all the spark plugs and coil boots changed out as they were nearing the recommended change times / typical failure mileage. Hope this fix will last for a long time.
Did you get your issue fixed? If so what fixed it
Did the fix work?
Thanks for showing how the software helps to diagnose issues, sure is a lot easier than it was back in the 90's.
I have had 7 Ecoboost 3.5 in different vehicles, Flex, MKT, and F-150 and found out the one thing they all have in common are plugs that go bad, especially running a mild tune. I found the problem though isn't bad plugs, but the plug design. If you noticed the center electrode is very thin, needle shaped. That thin point actually burns a hole in the ground strap and while the plug may gap properly that crater actually increases the gap enough to cause plug misfires. I also found gaping to .028 when tuned runs a lot better. I got into a habit of taking the plugs out every 30K miles and running a points file across the ground to remove the pit and then gap to .028. I replace the boots at the same time since they tend to cause misfires too. Never had a misfire since adding it to my general maintenance.
What boot are you speaking of?
@@powershomestead87 The plug boots that attach to the COP.
Wouldn’t it have been a twist if the customer would have had some counterfeit motorcraft plugs. After watching your video on that I wonder how many shops would be able to catch that.
Good information to know. Aftermarket parts are soposed to be better quality than OEM. Guess this is an exception. Great video.
Not for ford
Great diagnostic skills !!
Thank you so much for this information. It realy make life easier
Another great video. The scan tool is awesome too.
I use the exact same trim tool to remove the red locking tabs works great without breaking them. Thanks for the Videos
I cannot understand why *anyone* would leave a "👎" there is nothing here to dislike unless one is a shill for MSD.
They are fools or Chevy owners
People that don't like Ford maybe?
@@sporttracxlt I will go with "fools" since the methodology is not Ford-specific.
I’ll go with fool’s who currently running MSD coils on their EB
Troy Borysko that’s one in the same
This video was extremely helpful diagnosing and self repairing my misfire on my 2013! Thanks!
Great Video. Another lesson learned the hard way.
Your great! You do a hell of a job and ty for the explanations and being so thorough.
That was interesting as I had same problem with my 2015 Ford Fusion 2.0 L Ecoboost, also on No. 2 cylinder. Service dept changed the plug which never really fixed the problem. They never changed the coil. Problem never went away but remained intermittent.
Low amp probe also works great for quick coil ramp test
Great diagnose as always
Hi buddy love your channel. I bought an F150 used 2018 with 15,000 miles on it. At around 18,000 miles I took it to a dealer because I heard a rattle Coming from under the driver side or in the middle of the truck. I told the dealer it’s more prominent on cold starts so I left it at the dealer overnight so they could hear the rattle. The dealer got back to me and told me it was my cam phasers and they had to be replaced luckily they were under warranty so they replaced them. But when I pick the truck up a few days later I still noticed the rattle when I took it back to the dealer and left it overnight I purposely showed up in the morning so I could point out the rattle. Mechanic listened and he told me it was the exhilarate trans pump and it’s a natural characteristic of the pump to rattle for a little bit until it fills with fluid I would think there should be a check valve to keep the fluid in there it doesn’t make sense to me is he right
Ran a scan tool to see where the failure was occurring because I had the exact same issue.
I ordered plugs that were pre gapped, paid the extra fee for that. When I pulled the plug, the gap was 1 thou over what it should have been, especially running at an elevated boost. Small small detail that caused issues and limp mode for months, but the measurements were so close to what it should have been it was hard to identify. Power balance was definitely helpful.
Aftermarket is ok (for some components) but for vital ignition components, sensors etc I only use OE. I also do OE transmission fluid changes every 30,000 miles at $20 per qt, but it’s well worth the peace of mind. I use dealer parts and don’t have to make very many trips because of it..
Same here what was the issue I'm dealing with thesame problem right now misfires get on the gas it starts shaking new coils plugs new injectors
I still watch your videos even though I sold my truck a year ago!
Just bought a 2011 3.5 eco boost with 158k on her & Cylinder 2 is having a misfire but good to know to stick with oem parts for fords. I’ve been a Chevy guy for awhile now but kinda said screw it & bought a Ford so I hope replacing the plugs & coils fixes the issue. I’m guessing it’s time for them to be replaced anyways almost being at 160k miles
What's the story?
Videos are very informative. They helped me repair a few things on my 06 f150. Keep it up👍
Your video's are great ,you see so many more issue' that just dont show up too often for an independant. When i got to the part of the video where you revealed the MSD coils laughed. I have replaced so many of those and usually by the set. Why MSD would shame themselves selling those is beyond me,pure snake oil.
Great video.. love how you diagnosed it. Saved alot of time and money for the customer.
Would a different intake design help and do ya know of a better intake set up
Very good video. Great troubleshooting technique for this situation.
Gotta love it, bolt on that aftermarket crap and add a minimum of 50HP. It is funny every time I see that. Great Video!
Changed Coilpacks, plugs, did CAC mod, and it was STILL random misfiring.
Checked the intake an and Throttle body MAFS. Clean
However. The one on top of the plenum was completely caked with oil sludge from passenger side PCV.
Cleaned plenum air sensor. Installed oil catch can.
Runs like a scalded ape!!!
What did you use to clean the MAFS?
Awesome video! Been having some misfire in #4 .....hoping to not have to replace the coil, but if I do the link you provided is far less expensive than the local dealership.
I had this issue once on cylinder 5 on my 5.4. Replaced plugs(uggggh) and replaced the coil. Fixed issue for a while then it started again. Had to drive it as I was headed home from work trip, got home replaced it with oem coils, fixed issue but raw fuel caused catalyst code. Ruined the cats and had to replace. Never had issue since, that was 4 years ago
Thanks for letting us know how to do stuff on my truck. It's scary how hi tech my truck is.
I had an 89 Plymouth Horizon with a 2.2. I changed the plugs it had a horrible miss, it was an internal crack where the spark travelled through the porcelain.
I cannot think of what they call that piece inside of the porcelain, but they were brand new Champion plugs.
As always, great and informative video. Thanks!
Hey Brother, next time if you got the time, would love to see a current ramp waveform of the defective coil.
Thanks this was helpful to a 2015 F150 3.5 L V-6 that loves to knock. It would be more helpful to us if you tell us the spark plug gap you use, what was the torque you estimate when tightening the plug and confirm the cylinder numbering sequence. I've seen them numbered two different ways now. I am very frustrated with this truck, I only went Ford because the wife wanted it.
When I change the plugs I used a gap of 30
That looks like a good scan tool. I own HP Tunes, and it is an awesome tuner but a little "bulky". Having said that, yes I would buy it again. However, I really like the graphic layout on the one you use in your video.
What do you use and where can I purchase it?
2013 F150, Eco, 210,000 miles, ran synthetic mobile oil since original purchase and no issues...not even timing chain!
Mike
People are quick to knock OEM but it’s usually pretty good stuff.
It’s the original thing that required for your vehicle
I never buy non-oem parts for my F150 beyond shocks. Anything else, you're asking for trouble.
I use Ford parts when I can and when still available (can still get some things for my 95 F250), but when it was $120/coil (Canadian) at Ford and $67 for after market (and those weren't even the cheapest) for my 02 Explorer 4.6 with (at the time) 120,000 miles on it, I gave them a try. 2 years in and no problems. Maybe original Ford coils back in the day weren't that great either?
I own a 2012 ford 3.5 ecoboost aswell. Had the exact same problem with the factory coils. After I switched from the factory coils(which 2 went bad) to the msd's, and changed the spark plugs.I have not had a problem. What Doesn't make sense is that the coils would go on cyclinder # 2, just like mine. So what you are telling me is that if he had a factory coil in, the coil would not of went. Something has to be making these coils go bad. So what do i do, Switch my Msd's for factory again? Could anything else make coils go bad? As always, thank you for making these videos. Without your services i would not have to confidence to work on my own truck..
Wow, you get about 3 mpg better than I do. I have both sensors to change asap. Maybe it'll help some. My mpgs have always read 13.3 though.
Thank for the video, I own a Ford 150.
I missed the reference to the anti-seize on plugs. Yes or no in your opinion?
Love your channel.
(I drive an 06 F150 5.4 with 85K on it)
Yes but a very small amount
Hey Tech nice vid once again. Maybe if u wanted to dissect the bad coil you could do a continuity test somehow between the upper and lower part of the coil!
no the primary and secondary is separated by a gap.
Resistance test of coil windings is not a reliable test because you can't test the coil under load where the problem shows up. I flip the coil upside down and take a 12 volt incendscent test light attached to ground and stick it down the coil boot. Then start the engine and pull the tip of the light out and see how far the spark can jump. You can tell when you have a weak pencil coil. Don't let the coil fire without something for the spark to go to or you'll cause damage. Usually there is a reason coils go bad and it is usually from working to hard. Higher than normal compression and lean cylinder fuel charge can cause coils to fail prematurely.
When I run into mysteries like this I swap the coil and the plug to test both parts in one shot, but NOT both parts from one cylinder. Take the plug from #1 and coil from#3, or whatever cylinders give the easiest access on the engine you're working on. The extra minute spent swapping the plugs could save a lot more time.
True some ford parts are cheap in the dealer than amazon ... autoparts or autozone also works fine... i rther to buy oem parts are not expensive as many people think just call ford and ask the price... then u will compare with others... some aftermarket have been working for me fine.... use blue scan tools works also great... keep it mind labor is more expansive that parts itself
Multiple
Spark
Deficiencies
Great video as always Brian. So much chinesium made nowadays, I see it all day in 6.8 V10s in U-Haul trucks.
Also look for the scoring on plugs porcelain per ford's TSB. Which they state change all plugs and coils if you find it.
The second I saw the red coils I pretty much new what the problem was. 😬
thats how I felt. I saw MSD and knew.
When he mentioned the customer did a spark plug/coil change out, I figured there were junk aftermarket coils on the engine.
Had a similar issue with coils that favored Yellow in the brand and lasted a few weeks. went back to OE and never
did it again.
My customer bought 6 coils off eBay for 30$ shipped I told him it wouldn’t work no warranty on the job I installed them had coil codes on all 6 coils it ran fine 2009 caddy called him said no way I say yes way install 6 Bosch coils all issues are gone
My MSD coils work better than my FoMoCo coils. I also have to gap down my plugs to 0.026
A lot of newer vehicle issues come down to old dialectic grease on connectors and they dry out and get moisture in them and they don't work right, so always regress all your fittings for your wiring.
Nice job neighbor 👍👍
Great material!! Kicking myself cuz i just got my new MSD coils and new plugs, ready to install. Just bought a 2012 with 92k on it. Currently have a misfire on #3 and guessing that it's time for original coils and plugs to go bye-bye. Hope my coils do better than your client's.
How'd those MSD Coils work out for you?
Maybe the customer has the original coils in the luggage compartment? That would be nice. Hopefully he didn’t throw them out. Nice easy misfire Diag!
Good video and find on the bad coil
Awesome video, that is exactly what it is happening with my 2014 eco.. 🙏
Right around 60k miles?
I just own a used eco boost f150 2012 it’s misfire cyclender 456.I watch most of your videos I still need help. This is my very first Ford truck I own.
What happened?
Informative, as always! Thanks!
Very good videos that are very helpful.
Awesome Job. Thanks so much for taking the time.
Man i loved this video i have an F150 5.0 in dubai have same issue
Hey Brian, you’re the the best in this field respect brother always love your videos 👊🏿
i see aftermarket coils, i hope and not the issue, i keep looking at it.i hope and my ford flex was that easy.
My 2018 3.5 ecoboost has a P0316 code and a mode 6 test on forscan says misfires in mostly cylinder 5, but a few in 4 and 6 as well. Seems odd it’s all on one side of the engine. New plugs all around 5,000 miles ago. I guess I’m going to try swapping coils to see if it moves first…
Thank you so much for this video!
Did plugs to my 13 ecoboost 150 a couple weeks ago as I didn't know the last time they were done since I have only owned the truck for 12000 miles. Found almost all the coil connectors to be broken. Managed to save them and make them work but am wondering if they are replaceable and if you have a pn. Id really like to re-pin it rather than but connector the end together. Mines got 143000 miles on it and runs great. Its already had timing chains and phasers
Was the connector itself broken, or just the red locking tab? If it's just the locking tab, leave it be. The connectors are tight enough that it won't be problematic. If it is the connector itself, but it runs well, I would leave it alone.
Motorcraft part WPT-1284. It's a pigtail kit designed for you to cut off the old connector and crimp on a new one. BUT, if you're careful and patient you can use a pick to disassemble and pop the wires out of the old connector, then reassemble them into the new one. FordTechMakuloco quick tip #62 FTW
