If I had a nickel for everytime I heard "it's a new part" and then found it was just another used part from something somewhere. "But it's new to the car". That's what he did. It's his version of new.
I guess after changing the wngine, the next logical step would be to change the Ford Ranger.
Replaced engine bcs of a misfire ? Ya why not , when it comes for an oil change I don't deal with it ... I just replace motor 😂😂🤣🤣🙄
It's scarey , isn't it?
I agree with not believing customer claims.
I had an over heating Land Cruiser with a “new” radiator.
Talk about going down the wrong road .
Turns out the bottom tank was plugged. Had an “old”
new looking radiator.
Keep up the good work.
Love your mistakes, makes you much more human and believable.

One time long ago I changed a motor in a 84 dodge ram 4x4... Original motor was a 318. It had a bad ticking noise. Only 68,000 miles. Just bought the truck like that cheap because the previous owner was fed up. I had a known good 360, so I did the swap. Started it up and it had the exact same ticking noise. Well I went underneath and the source of the ticking, took the splash shield off from the front of the transmission. No noise HUH. It was a warped splash shield. Straightened it out and walla fixed it. Live and learn. Boy I felt dumb. But hey it wasn't my only screw up
Lol back in the day first car was a Plymouth fury 3 with a old 318 engine in it that time would would skip time just by looking at it worse engine ever made
Another good video and I walked away knowing more about troubleshooting misfiring engines!
Engine replacement for no reason. Sickening.
There's one on here where someone pulled a 4.7 Toyota because it broke a timing belt and bent all the valves. Except a year later the guy tore the motor down and it was perfectly fine; just needed a new timing belt. EXCEPT after sitting outside for a year the cylinder bores were rusted and pitted beyond repair.
Just based on the shape of that coil pack I assumed it was a waste spark system with three coils. But if that is the case, why would only one cylinder be affected? Is it possible for a waste spark system to affect only one cylinder? Am I wrong, are there six coils in that coil pack?
It is a waste spark system . I've had several waste spark coils in the past loose one leg only . Not sure why though
@@WrenchingWithKenny Ah ha! I get it. There is a short to ground on the secondary side, between the coil and one of the two companion plugs. That means one plug continues working as before, and the other plug gets bypassed by the short to ground. One cylinder fails.
@@WrenchingWithKenny for example, my 6 cylinder has a single pack with three coils on it. On each coil is a primary and secondary winding. Think of the primary and secondary as a transformer, which it is. The secondary is your spark plug wire attached to the spark plug, which ignites the air fuel mixture.12 volts primary- converted to the high voltage on secondary via the transformer action of the coil pack.As@spelunkerd said, if you have no spark at tower testing with a test light, check companion cylinder. If spark on companion cylinder, you have primary control- you need a coil pack. Personally I would change the spark plug wires as well.
If you ever need to put an engine in one of those 3.0 rangers you buy a Taurus engine and remove heads and put ranger head gaskets on. Junk yard will tell you 1500 for an engine for ranger and 500 for low mile taurus. The head gasket on ranger has extra hole on them that allows coolant flow to heater core.
Good job diagnosing however, just so you are aware direct injected chevy truck motors will misfire just like a failing coil when the fuel injectors begin to fail so dont let those fool you should you ever come across one
100% agree with you on not listening to what someone has done before. It can take you down rabbit holes you don't want to go down. It prevents clear thinking which is the one thing we need to troubleshoot.
Also remember, new parts can fail too. Just because someone put a new part on doesn't mean it hadn't failed.
Twice is too much.
Well in airplane school you not only find the failed part, but also the reason it failed. Brother kept having his rockers broken where the push rod sits...twice. the third time it happened I discovered lash in all the rockers and simply tighten them snug to the push rod. Thought was why didn't the mechanic who serviced it didn't bother. Anyway my brother then stated the car never had so much power. Anyway, he must mean parts from Auto Zone or something.
@@brahtrumpwonbigly7309 diagnosedan (who is going to pay for this ?) have a look
Had one of these rangers with a persistent cyl3 misfire. New plugs, new wires, harness ✔️,injector ✔️...
Finally replaced the new autolites with ngk problem solved till now
@@jaws978 YA Plugs can make a HUGE difference. I bought a 1963 charger RT with a 383 mangum. It ran good but when I decided to tune it up I found someone had put autolight plus in it and my mechanic friend told me to switch to Champion. WOW, what a difference, Certain cars need certain plugs for sure.
Good stuff you do a great job on giving your explanations you would b a great teacher for the kids wanting to learn mechanics 👍👍
A tip for using the Snap-on Solus tool and diaging misfires on fords: The drive cycle misfire counter is not a real time counter. What I tend to default to in this case is the cylinder contribution test. It's in the "functional tests" submenu in the engine menu. While it isn't a misfire counter, it does tell you in real time when a cylinder dies, and I tend to find it most useful. Fords that are too old to support Auto-ID on that scanner though will show the test as an option, but they aren't compatible, so the old school methods of testing for misses have to be used.
Mode 6 TID 53 will give you cumulative missfire information as well.
But, Why no check engine light?
@@tonywestvirginia because Ford was real casual about it.
@@jamesgeorge4874 c. C
As a dyi guy I learned long ago to, instead of going to the parts store and looking up the part and purchasing, to remove the part( water pump, fuel pump,...), take it to the part store and match it up bolt hole pattern, connector locations and attachments, general shape etc. If it didn't match exactly and the counter guy told me well that's what's in the book, I'd send him back to check the shelves and invariably he come back with the right part.
Its good to compare parts, however sometimes the part in your hand is a known issue, with a track record of early failure, and has been redesigned to correct a specific issue. As a professional, i see redesigned parts that bear little to no resemblance to the original. But install it and it works. Just bear that in mind.Sometimes looking different is a good thing.
New does not mean good. Especially these days. Everything is made as quickly and cheaply as possible. QC is not what it use to be, in fact I’m not sure if it’s even done most of the time.
Where do pool cleaning companies keep finding these trucks?
Good old waste spark spark system Kenny. I have a 2007 Ford Ranger , has happened twice to me. If a spark plug wire opens ie, infinite resistance the spark has to try to find a way to return back to the coil. It will find a way , probably through the coil. The result is a bad coil as well as a bad spark plug wire.In these situations, replace both the coil and the spark plug wires. And you are correct, watch the coil pack replacement. some are 3 nut holddowns and others are 4.Think proper terminology is type 1 and type 2 coil pack. great video as always , Thank You for sharing.
I have had a really hard mis-fire in my 1998 A6 2.8. It initially only happened at very high load (trying to accelerate up a hill, locked in top gear from 13 - 1400 rpm - I know) usually only once or twice but then got worse, similar conditions but less load and more frequent misfires. I thought it would be the coil pack, but I had an exhaust leak in the flexi between the after the 1st o2 sensor but before the cat and 2nd sensor. I stopped the leak and the misfire did not return until the other side started to blow and now is gone again. A leak there seems to upset the fuel calculations so I assume it was trying to too rich or lean.
Yeah, when I get an oxygen sensor slow response error, I now know it is a hole in the exhaust.
@@dennisharvey4499 When I bought it 8 years ago I knew I was finally making the leap to digital motoring after clinging to analogue. Luckily I hit the sweet spot between - it is OBDII so the scanners work but it has no check engine light and doesn't give me any codes when it happens. Took longer to figure it out but I love that my car is like 'Whatever' and keeps rolling..
It's great watching skilled honest people doing their trades
Amen!
Yes good ole plain men doing what they like doing no Drama no murders no stealing just good mostly honest men doing there thing got to Love It
I once changed my roofing shingles because I had a leaking pipe
Hahahaha😆
Hell 40 years ago I bought a new house because I had a Bad Wife.
@@williamtaylor628 Probably had to cuz the bad wife took the old one!
Did it fix you pipe?
Right changed my oven cause my wife said she could cook!
Beautiful verbal explanation of different symptom ignition vs fuel injection..
"If that is the worst thing that happens today, it's not a bad day." What a quote! I may be using that in the future. A lot!
Yep. As a coil heats up it will usually misfire more often.
I've heard the hard miss Kenny was describing called a fish bite miss and as mentioned usually it's an ignition problem.
Firing order and spark plug wire order is the same on both coils. It's the coil plug wiring that's different. Gotta love engineers!
My Nissan Frontier 2001 did that and could never figure it out until I got the original timing belt replaced, reason I didnt get it replaced was because the car just hit 105k miles in 2023 and the manual calls for 105k interval change for the belt BUT down the paragraph it tells you 105k or 7 years which ever is first and its a miracle the belt didnt snap in the 22 years it was turning now its so smooth that I thought I was driving my dad’s new MINI Countryman
D'oh. Computer controller. Throttle position sensor. I had a Ford E150 with this kind of problem.
That's the way I am too. I think people take it wrong when I tell them that I don't want to hear what they think is wrong. I've seen vehicles with many new parts and the owner is saying why the fuel pump, the filter, and even the fuel line is new but they still get no gas. You brought it here and I'll fix it and to do that I need to check a thing or two. Turned out the shaft between the cam and the pump was wore away. The hardest to find problem I had was a simple glove box switch that had a broken mount. I knew which circuit but it powered nearly everything within the interior. I found it my second time through on my hard target search. I checked the operation of the button by hand and found that the whole switch as a unit moved. Otherwise how would you know the glove box light is still on with it shut. Shit bird I worked with spent two days working on the car in vain. The third day boss man calls over, 'Hey J, see if you can figure out what's wrong with this car'. I walk up and inspected it seeing everything under the hood is new and replaced. With that I proceeded to try a compression check. Lo and behold, the second cylinder I tested had no compression.
I'm an old-timer, and I once found the fuel pump cam lobe worn flat on a Ford pickup with a flathead V8. The cost to replace the cam was insane. I wired in a $30.00 electric pump and the customer was delighted.
I got a bad coil from Az , Av, and Or- parts all made in CH**A. SO I bought one from a Ford dealers and solved the problem.
The good ol fish bite misfire
If you were to ever get a ranger, the v6 is really your only option.. better yet get the mazda b4000. Same thing but better 😆 and cheaper
They probably did put the coil, timing will mess up ,chain timing belt sprocket, mess up the coil in a month or 2
Sounds like someone used the extra large parts cannon on that one . I had been in the industry for 42 years, and you’re absolutely right. Don’t believe what you’ve been told or what somebody else has diagnosed. I would politely listen to the customer on what they had done or thought. Politely listen to a tech from another shop and what they did when they couldn’t find the problem. And even politely listened to one of my own technicians when they were out of ideas and couldn’t find the problem. Then I would say, “ I want to diagnose it myself.” If after a while I was stumped and couldn’t find the problem, I would step back take a deep breath and say, “ Ok, let’s start from the beginning again, one step at a time. I’ve missed something “. When it comes to misfires I would tell my customers and technicians that there’s three basic types. Electrical which happens abruptly like a light switch, on/off, now I’m good now I’m not. Fuel related which happens slowly like water in a garden hose. Then a constant or dead misfire which could be electrical, fuel or mechanical. 😊😊😊
Once again, thanks for the lesson, and the ride along!
The is by far my favorite channel ive discovered in a long time thank you for stopping to explain your thought process, it's super helpful while trying to learn how to diagnose problems.
Thanks for watching 🔧
I always keep the old parts off of jobs that I do. They come in handy. I just changed the cam and crank sensors on the 4.6l Ford. Drove it for a while and it started doing the same things that I changed them out for in the first place. Including codes. So I put the original parts back in. Fixed the problem, like forever. I'm suspecting, in hindsight, that corrosion on the contacts was the culprit. The very act of changing and scraping the contacts in the process was the actual cure. And who knows what's going on with the new parts. Yes, I inspected the parts upon removal and all of the seals were intact and nothing was leaking. Like your thoroughness in your work. I'll be watching your videos for future content!
The plug boot can also grow a carbon track, the Ford F-150 Eco boosts are notorious for that. Jeep wranglers can have a tiny hole burned through a plug boot that is hard to spot, sometimes watching in the dark works. Good job!
Man that’s nuts that a guy replaced an engine for no reason. But as soon as you said it’s missing and it had new plugs and wires i was like its the coil. I have one of these pickups and I’ve learned a lot of their quirks and the coils are common to go cause a problem
They could have put in the same wrong coils and return them
You say engine is dead cold. But reference it as a motor? Please say engine
Awesome channel. Very enjoyable and informative..
As an owner of a 98 ranger with the 3.0 and had a misfire issue, my problem was when it was changed to aftermarket wires, they were garbage. Changing to Oem ford wires solved the problem.
Nice work! Yes, never believe a customer or the guy who couldnt fix it, and just work with the understanding you're starting from scratch. I was sold a passat wagon a few years back that had an issue with over heating, shop the owner took it to replaced the thermostat, and still over heated, so they said its going to need a new engine (no idea where they got that from) when I was sold the car, they told me the info, but I just went in blind like normal, pulled the thermostat, it was rated 20-25 degrees higher than the operating temp of that engine, put the correct one in, fixed. My buddy is still driving as a daily to this day.
They probably returned the coil twice to the parts store. Put old one back on.
Good info on the hard hit vs soft hit, never thought about it but have experienced it many times. I have a 3800 series 1 Buick and it was doing exactly the same, random hard hits especially at idle in gear. At first thought it was a plug, they were a little old anyway. New plugs helped, got rid of a misfire while accelerating but still had a random bump at idle. Ended up being a bad coil. Had an extra in a box and swapped it in. Luckily it happened to be the first one I changed. Coils right up front, super easy fix.forgot to mention, this bad coil still worked but ohming it showed infinite resistance in the secondary. Must have been a tiny break in the wire toward the end where the spark could jump it internally.
Really surprised you didn't mention using OEM parts. It's critical especially on Fords that OEM parts are used on ignition system including plug wires. Cheap chinese after market ignition parts are junk, even when new, and cheap plug wires can ruin ignition coils as it makes the coils run too hot. These coils are not just coils, they have ignition modules built into them which is what generally goes bad in the first place. That first coil you put in there has a different firing arrangement for the firing order, and it's the ignition module that determines that order. Always always use motorcraft ignition parts for Ford, otherwise expect trouble even if it's not right away, odds are cheap parts will NOT last even if they do work right from the start. If those are cheap wires in there good luck them lasting anymore than 10,000 miles if that.
I think they bought the cheapest coil online or parts store. Chinese b grade. A grade is best b next c is why buy this and d grade is guaranteed not to work
you called it and sent it right on .
Nothing like experience!
Aircraft Quality troubleshooting approach to basic automotive issues . LOL . Another good informative video .😎
Kenny, Great Job, I did the same for OMC Johnson/ Evinrude 25 Years ago, I enjoyed my job, doing the Same in Outboards your approach is great! Tom W
Good job. I suspect someone did the same thing you did with a new "wrong" coil, then just put the old one back in and still claimed new coil was installed. Maybe.
Could you do a review/comparison video with the snapon solus, and that new launch you got? Great show sir.
Thank you. It isn't apples to apples, but im working on a comparison video. Keep Wrenching
I like wat u do n how u do it. If only i had a guy like u near me..
Yeah. New "junkyard" coil...
Appreciate your clean language sir. Shows quality.
They probably put a used one in it
YT sent this video my way and i thought for sure it would be my saving grace as I'm currently dealing with a 2000 explorer and a misfire. Changing between old and new coil, wires and plugs i haven't solved my issue. Got order wrong and that's when things went really bad. After getting the order back correct I've gone from an idle misfire to the vehicle trying to die when put in gear. I'm afraid of internal damage from running it with the wrong firing order
Hi, It's Mrs Wrenching! You should go on the Facebook group Wrenching with Kenny (answer all the questions) put the year, make & model of your vehicle in your post. Be sure to include what is happening with your vehicle & what you have done to fix it so far. There are a lot of techs that may be able to help. The link is toward the bottom of the video. Keep wrenching!
PS also let everyone know if there is an active check engine light & what it is 🔧
@@WrenchingWithKenny Thank you. I'll look it up
Just because its new don't mean its GOOD, probably more true now than a few years ago with so many cheep parts out there. I am a new subscriber and still welding the spanners at almost 70 years old. I enjoy your channel very much and am still picking up hints and tips from you and Eric at South Main Auto.
Yeah, DOA is a real issue for me these days.

Intermittent injector misfire.... Sticking injector... Just something I would check withy scope...
First time nice fix.
I got one for ya...2011 gmc 6.2 denalli....been at dealership for 13 months..
Granted during pandemic parts hard to get...finally rebuilt engine under warranty....since end of June til now I have picked it up 15 times saing it was fixed...random misfire everytime...they changed rockers...lifters...rings (2nd time)..cam phaser...plugs ...wires..intake..converters...O2 sensors...picked it up again Monday morning....went 40 ft and misfire again..(ck engine lite on each time I picked it up....left it there again.....any suggestions.
I have a 93 Ranger 4L V6 Misses bad at 3K RPM whether driving or just reving engine. Replaced everything.. Dealer can't find the problem.. any suggestions??
This is one of the best misfire diags i have ever seen! I learned new ways to look at things on this video! Thanks!
Thanks for the hard and soft misfire thinking So hard to track down at times engine management boxes etc I did hear of one proved to be a signal from a front break sensor
Just came across your channel Kenny you now have a New SUBSCRIBER!! I work in the Automotive field and have worked on cars and trucks that was Miss Diagnosed nothing new or bad New Part.Good job Kenny have a Great Day.
LOL ... ive seen a shade tree mechanic replace a Truck engine .. because of a faulty 30 dollar fuel regulator!!!!! ((( mind you he had changed most everything on that old ford truck first !!)) He really liked that old truck too ...
But was to stubborn to pay anyone to help him with it .. ect ect ect
Great video Kenny.
i replaced fuelpump on 2,5L subaru legasy 1998 mod gasoline ( ej25 engine ), ( brand new engine ) 0 miles. from promar engine, completly rebuld, fuelpump i bouth was not orginale, and was 3.3 bar, and i think orginale pump have 3.0 bar. Notice nothing when engine is cold, but when its hot on low rpm and u press gas pedal fast, then engine stummels, and looses lots of power, but runs smood if u press gas pedal slow. Its new fuel injectors for 600 usd, wit warranty, 5 years old plugwires, brand new iridium sparkplugs, changed coil ( used one ), and fixed some loos pins that goes from enging to cpu. so all pins are tight.
maby i shoud get a orginale fuelpump in gas tank?? what do you think?? also replaced fuel filter, and air filter.
om 2000 rpm on hot engine its runs GREAT, iven ik u kick gas pedal to the floor. also replaced fuel pressure regulator. ( new )
Great information on recognizing a ignition to fuel event.
What if the misfire came from a open valve how do you think the engine sounds like or how do you think it feel? Thank you great video I have a 2001 ranger
I had a 2007 F150 that had a chronic misfire for YEARS. It wouldn’t throw a code to tell me which cylinder it was. I didn’t have a code reader with PID’s. I finally took it to the dealership where they determined it was a plug with a damaged insulator.
My Mothers '97 Taurus had a constant misfire on #5. We took it to 2 shops, the first shop couldn't figure it out and the second shop (Ford Dealer) wanted to replace the head gaskets. I finally took a look at and figured out it was a bad plug wire. When I switched the plug wire with another cylinder, the misfire went to that cylinder. $5.00 fix. By the way the engine was an FFV like this Ranger had. Aren't the coils set up in pairs and fire 2 at the same time, making the coil pack what I call a wasted fire system? I believe you could switch any 2 plug wires on a coil pair and it wouldn't make any difference?
I had a misfire in my 2008 Ford Ranger (2.3 L 4 cyl.). We were pretty sure it was the ignition module. I changed it with two different after market units and still had a misfire. The plugs and wires were changed within the last year, so I didn't suspect them. When I purchased an OEM module from Ford, the misfire cleared up and I have had any issues since.
I know a lady who's 2005 Ford Focus developed a "stutter" (which I eventually diagnosed as a faulty throttle position sensor). Initially she took the car to an official Ford dealership where, after putting the car on the diagnostic computer, they recommended _purchasing a new car._
Pity the owner didn't go down the route of a 50 Euro Cheap OBD 2 Code reader as even those would cough out the General Code and more importantly then the specific code relating to what's miss behaving on the diagnostic side, my daughters car was throwing a 'General' miss fire code on and off, i changed the Plugs, it didn't help a month later it threw up code for one of the two Crankshaft Position Sensors bought that one and it was Sorted, a year later General and specific code or number 3 Cylinder ,i swapped around the Coils from 3 to 1 and it ran away and the Code Jumped to number 1 and also threw a Code for Number 2.... I went for what i thought was the Nuclear Option... I changed BOTH of same and the problem was Sorted, the car is twelve years old a Hyundai IX 20 so i wanted it to be reliable for her so an extra few peace of mind ... Problem solved, but firing a Motor into a car that's Serious... Great Upload...
I saw a guy throw an MAF, full tune up, intake gaskets on an F150 with this style coil. I put the scope on it, and the waveform showed that every now and then, the #5 circuit of the coil would drop out.
Could it be the plug wire wasn't securely attached?
That is always a possibility.
Well that's disappointing. Usually when I take my Heep to the mechanic I give him some notes about what I observed or any tests I did. Like "Drove fine on the way home Friday; did not use Sat or Sun; Started rough Mon morning; gages looked normal nearly no power; No milkshake for oil; no bubbles in coolant overflow. Could not see any arcing while shaking wires in zero light condition. Please diagnose and advise". Kind of sad thinking he might not be reading my letters.
True that Kenny, never rely on what people tell you they've done EXACTLY correct. You NEVER really get the true facts. And, you have to do like you so thoroughly do, and diagnose it yourself !!
New motor for nothing..
I just bought a 2000 Montero sport for $1200 from a "friend" after handing him the cash I discovered that the harmonic balancer bolt was backed out. I had gone 2 miles. I said I wouldn't have bought it knowing that. He said I was trying to rebuild it. It was bound for the junkyard if driven. Luckily the threads on the crankshaft were good. Pulley is scored and galled and probably the timing gear it mates to. I am retired and it took 4 months to save for my buddy deal. I don't want to remove the timing belt but probably have to change the timing gear. Folks saying I am overreacting just tighten it. I was called a perfectionist by the x. I said who else would you rather have working on the aircraft your rear end is riding on. With limited resources I must make it count. Not working on cars for years because I could afford new ones then changing major parts in the yard just reminds me of younger days when I was poor but didn't know it. I will make it run well and will not stop. I have been without a vehicle 2 years and COVID I isolated now I will make it reliable because I have road trips to do. Not too much invested if it dies on a trip to walk away! It's an adventure.
They have same scanner u are using....#1 cylinder misfire fired 25 times....raise rpm and mis goes away?????
Let me know what u think
Hey I have a 2002 Buick rhinov and it has a misfire cylinder. 2 problem it was misfiring before I did the fuel injectors. Both shops that have worked on it told me it was the fuel injectors. I had a suspicion. It is the coils or the spark plugs. And I have not replaced those yet. But when I first had it worked on the spark. Plugs and wires were all brand new
Year, model and serial number. Don’t know coil wiring? Please try looking up company name and search by model and they always have info to look at and download. Hope you didn’t charge your hourly rate for coil mistake. Not customers fault.
Perfect advice! go off the complaint that's how I work and I'm just a diy person,, atleast they put a good motor in, nice video!
Without watching... intake manifold gasket. They never changed it when they replaced motor.
The numbering of the cylinders on those coil packs is important.
Make sure.
The OEM part has numbers printed on it.
The cylinders on a Ford are sequential per side.
Check the service manual or look it up online.
The numbers can get cleaned off the coil pack pretty easily.
Find out what you have for your build and calibration.
Ford literature has been helpful in the past and they have updates if you check for that too.
I've seen the new parts for tune and driveability, from an independent repair company returned to the customer and motorcraft parts made it run like brand new.
Assumptions get made by people and their expectations during maintenance and home repair.
Checking what's right for that build and correcting it is half the job.
When those coil packs first came on the V6 distributorless, I wiped some dust off and noticed the printed on numbering sequence.
I've seen a few times where cleaning the engine compartment easily washed off the indicating numbers from the coulpack.
Nobodys perfect Sir if you were close to where I lived I'd take my car to you.Alot of your shops are cheaper than the Dealerships.Its a roll of the dice if they know what they're doing.I wouldn't hesitate to take it to this Guy.You can tell he knows what he is doing.Keep posting Sir I'll keep watching
I had problems on a Windstar with constant misfires! Wound up being cracks in the intake! 3.8L V6 was a plastic intake!
I had a Citroen Berlingo van, which if I missed a service, it would switch the MIL light on, and cough a bit, whilst I am driving.
The Berlingo has a 1.6 HDI 4 cylinder engine. But the diagnostic tools will give the code for a cylinder 6 misfire.
All I would have to do is either get it serviced, or erase the error codes. Then it will run fine.
This made me think that the computer on the vehicle is set to show up problems, that do not exist, just to make me get it serviced, if I had forgotten.
Great, real-world video. Thanks.
#1 problem = FORD. You don't fix fords, you SCRAP THEM!!!!!
I had a VW Beetle.my headlights went out.Checked the fuse,replaced the headlight switch ,then replaced the dimmer switch. Still no headlights. Left it at the shop . They called me right away to come get it.Both headlights were burned out on dim!Fix the obvious first!
ford 3.0 with a misfire. 99% chance spark plug wires and coil pack, most often caused by not changing the spark plugs and running with a large gap. but the wires were always a problem.
When customers would bring in their own parts, especially used or from a dodgy parts store, I would say to them, a little sarcastically, “ I hope that’s a six pack, we may need that many to find one that works properly” 🙄
When presented with a coil design like this an easy way to dx the coil is swap the wires to opposite sides from coil. It uses a waste spark system. So if misfire moves from 1 to 4 the dx will be complete. And if you have 2 misfiring cylinders on same contributing coil then also pretty concrete. Chrystler products and others also use this design. Hope this helps. Also, grounded test light to visualize missing spark works with wire pulled off, but may have to power brake the engine and not get run over 😆.
That coil that you took out looked used ? Maybe junkyard,eBay special, lolol! I have told tech what I have done as I screwed up repair! Not telling tech what to do! But rather my stupidity up front!
Don't just look at plug wires. Check them with an ohm meter. Should be 5k-8k ohms per foot of wire.
Some motorists you will never understand. he swings the engine and lies about coil replacements?? he's only lying to himself...and his wallet. I'll just assume the poor shlub was having some brain-fade or something like that.
