So the previous owner of my V10 Ex had all the plugs changed and some of the coils needed to be changed at the same time.
Some have a yellow sticker on them. Some are plain black. The yellow ones say "Motorcraft" plainly on them.
The black ones look identical to the ones on my wife's Duratec 3.0L V6 in our Mazda MPV. They also have a Motorcraft part number on them.
I have a 2000 f150 with 198,000 miles. The lite on the dash came on, "service engine soon" , I had the codes read and they said the coils are going bad.
View 2 RepliesUpgrading ignition coils on 5.4's? Looking to upgrade mine and only came across a few and the reviews are mixed. I am primarily looking to smooth out the idle and gain some minimal power and maybe get a flicker of a gain in mpg.
View 3 RepliesWhat would cause me to have to replace several of the same ignition coils in less than two years time? It seems like it always happens after I purchase gas.
View 1 RepliesI have 2 spark plugs not firing. one of the three ignition coils does not fire, the other two do, is the most likely culprit be the ignition control module? car has the 3.8 motor.
View 4 RepliesI haven't had a check-engine light yet, but at idle, my 1996 Maxima has a sporadic misfire -- there's no rhythm to it at all. Does this sound like a symptom of a coil going bad? What would be a good way to test them without having to replace all 6 of them? The car has about 175,000 miles on it. I just put in a new set of NGK iridium plugs, and hope I didn't damage any wiring in the process (that doesn't seem likely, but I guess I can't eliminate that possibility).
View 16 RepliesMy husband's 2001 Buick LeSabre had an ignition module and one ignition coil replaced in March. Yesterday, the car broke down, and the mechanic told us that the new ignition coil shorted out the other two coils. Is this believable? We've been using the same mechanic for several years because we trusted him and have heard a lot of good things about him, but this seems kinda fishy. This car is not one of the GM cars that was recalled.
View 10 RepliesI have a 63 dodge pickup with a habit of burning out ignition coils within 2 weeks. It's happened with the slant 6 motor, it's happened with the 318 v8 and its also happened with the current motor a 440. I have changed the ballast resistor, and the ignition switch, as well as the starter solenoid, and all related wiring.
View 4 RepliesSo on Thursday night I replaced all of the plugs and boots on my 01 v10. I used Autolite 103's and Autolite boots. On Saturday the truck threw a code for cylinder 8. I bought a bag of 8 used coils off a buddy who has a mustang buy a few months ago so I put one on, cleared the code and the miss went away. On the way home tonight the truck started missing hard, but no CEL. I use torque, so i did a scan anyway and it pulled a code for cylinder 7. I haven't been out to troubleshoot yet. Could I have done something wrong for 2 coils to go in such a short amount of time? I followed the write up in the tech folder. Used proper torque specs, dielectric grease, and anti-seize on everything.
View 6 RepliesI have 06 XLS with 56,000 miles and about 3 weeks ago the check engine and VSC lights came on. It was fixed, a ignition coil on the 4 cylinder.
Now driving home today the check engine and VSC lights are on again! I was wondering should try to get the dealer to replace all the remaining ignition coils ?
Plus I read their was some type of manufacturer defect on the original ignition coils from the factory. Why Toyota won't recognize this issue ?
Two ignition coils in a little over a month . My first Toyota and I'm rolling with the punches .
I have honda civic 2005 Lx with 170,000 miles. I noticed increased RPM about 1.5 with cold start but no missfire. I attempted to take out ignition coils to see if genuine ones solve the issue. It is very little rainy today with high humidity. After I put new ignition coils, I noticed increased shaking with misfire. I have not touched anything except for putting in/out coils. I ensured the position and connection of the coils. Is this anything with humidity? I did it really quick without much exposure to the rain. How to resolve this issue? at least return to previous condition?
View 7 RepliesI need to know what the resistance should be on my 2002 Echo's coils. I have an intermittent sputtering problem and it's driving me nuts! I put E3 spark plugs in the car about a year ago to improve the power and economy (it was on the original plugs at 160k miles!!) and they did work a lot but not long after that the sputtering problem started.
The car does have a code for the pre-converter O2 sensor but I replaced it, cleared the code and it keeps coming back. I have not pulled the codes recently but will in the next few days.
I've also read that the fuel filter is inside the gas tank but there is an access port under the back seat. I doubt that would cause the intermittent problem but I could be wrong.
I have a 02 ex 118,000 on it, not a every day driver, mostly weekend and camper towing. The truck was running great, stopped at a light and the engine started hesitating, the od light was flashing, and then it died.. started right back up no od light, but was still hesitating/missing took it to a local shop, they hooked up a scanner and said that several coils were misfiring. My question, replace all coils? go with oem coils, or aftermakert?

What is the gear ratio?
I am looking to replace the 4x4 offroad sticker on the side of the bed and wanted to know the dimensions. I've been looking on eBay because dealer wants way too much for stickers. just want to make sure I get the correct size.

View 3 RepliesI have looked at many of the other treads and I can not find the answer. How do I locate the keyless entry code sticker in my 2008 F350? I just bought the truck used, I do not have the card that is delivered with the truck and I don't want to pay the Stealership to hook it up to there computer. I am looking for the RAP or the computer module as it is called in the owner's guide.
It is not behind the glove box, there is no longer a fuse access panel under the dash like the earlier SD's, the drink holder under the upfitter switches does not "pop out." Before I start with any tools, I am looking for input.
None of my 4 keys will operate my ignition switch.
It's stuck in off position. Steering wheel is not locked and I have pulled pretty hard on it to see if I could get the ignition switch to turn.
I have a new switch on the way but I have to get the old one out and don't know how to get old one out if I cannot turn the switch to on position.
Started truck and turned the wheel far to the right and shut the truck off to get better access to the grease zerks. Now the entire column, ignition is locked up tight. I can't turn the key, remove it, anything? Thoughts? I'm stuck
View 14 RepliesNeed to diagnose:
- Truck idles a little rough sounds a little like " puff , puff ", when put in reverse - still sounds the same ( looping hesitation )
- When accelerating feels pretty good until about 40-45 then it starts to shake , shudder and loose power. Shakes and shudder pretty violently.
Did a full ATF fluid service - no improvement
Aside from that it does not seem to have any other shifting issues at all. Problem is intermittent. Throughout the day it may run fine, and then at another point in the day it runs like poop when hitting 45+.
Could it be a bad Ignition Coil Pack ? Car has ZERO codes appearing - would either TC or COP set one off ?
Here is a pic of the one COP that I found does have a crack on the top ( passenger side ) - not sure if that could cause the truck to act the way it does.
