I am going to change the plugs to start trying to fix this. How do i remove the coils from the plugs. I cannot get the connector off and do not want to break it.
View 7 RepliesReplaced plugs and coils after I got a misfire on cylinder 2. (cheap made in china coil packs off of autoparts warehouse)
Also, plugs had 30k miles on them with original packs. Got it again.
Replaced coil on cylinder 2. Got it again.
Bought Denso double platinums. Got it again.
Moved coil packs around. Misfire on cylinder 4.
Checked plugs, good dry non corroded. Its always 2 or 4.. not 1 or 3
Slow drive with less than 30% gas pedal action it runs "ok". If I go uphill or need to step on it, not happening. Bucks like a mule.
I dont think its the fuel injector... Ordered the red audi packs off europaparts. Might need to check connections. what do i do?
I've been also reading that it could be the cam follower. I'm willing to check it and then force the dealer to fix it under the extended warranty, but if its broken I cant put it back in. The dealer is 50 miles from me.
It happened a morning I was out of gas and used .... regular! But did put in super right after that. I had spare regular gas in a container (fresh) for the generator.
Then used fuel additives. I have also been using fuel additives every other fill up just to protect injectors. I know it wont do anything other than that because of direct injection.
I 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 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 RepliesCode: P0303 Misfire on cylinder #3.
Swapped coil from cylinder #3 to cylinder #6 and fuel injector from #3 to #2.
Shows misfire is still on #3. Plug looks normal tan brown.
#3 is the middle cylinder closest to the firewall I take it.
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 3 RepliesOK. I'm getting a P301 code on the OBD in my 2000 Expedition (5.4 L). Already replaced plugs x 8, coils x 8, & fuel injectors. Still have rough idle when it starts up, usually for a few minutes & then it's mostly OK. Maybe a small rumble now & then when @ a red light, etc. Replacing fuel filter & all 4 o2 sensors tomorrow.

View 6 RepliesSo, my 2014 Tiguan started having a misfire on cylinder 1. It has 35000kms with 80% highway. I have an APR stg 1 tune. The misfire started at 30,000 or so. I took it to the dealer and they said I would have to get the tune removed before they could look at it... I did some trouble-shooting on my own. Moved coils, stayed on #1. Replaced coils. It came back. Changed plugs, stayed on #1. Drove three hours to get the tune removed and back three hours... The whole week the dealer has been hesitant to say they will do anything on warranty. Spent most of their time trying to prove my changing the plugs and coils caused the problem. Finally, yesterday they put a call in to VW Canada who agreed to change the injector and manifold. The dealer called to say I need the carbon cleaning done. Of course I do... I agreed to it but asked for pictures. I change my oil every 5000 kms and drive almost all the time on the highway.
View 6 RepliesA few days ago, my CEL came on when I got to work, I assumed it was a misfire because when I got off work it was off. Now, I just got to work and my CEL came on when I left my house. I have been noticing engine sputtering/wastegate when I'm around 2-3k rpm, hovering around 20-35mph, after that I don't notice it. I bought the car used at 39k miles, the 40k service, nor an oil change has been done since last september. (not sure if that's a factor). I've skimmed the forums and head it could possibly be the spark plugs/coil plugs/ or turbo.
View 6 RepliesI have a 2009 TSI/2WD with 68k miles on it which we bought brand new. The car has been relatively trouble free for all these years and my wife loves the car.
Middle of the last December my wife calls me and tells me the "Check Engine" light came on while she was driving.I told her if there is no unusual noises or any warning lights blinking drive the car home and I'll take a look at it when I get home.She said everything looks normal and nothing unusual.
Long story short,I came home scanned it with VAG-COM,found random misfire codes and spotted the oil leak on the garage floor and saw where it was coming from.Yeah you guessed it right, it was the Crank Shaft seal.
I went ahead and replaced it with new one from the dealer and a new PCV breather too.Started the car after I finish No leak,No check engine and everything was fine.
Until two weeks ago again the check engine light came on.went ahead scanned again and this time it was P0300,P0302(RANDOM AND CYL.#2). There was no visible misfire that I could feel so I cleared the MIL.I also did swap the coils to make sure it wasn't coil related and again it stayed the same as before.Spark plugs have been replaced 3 months ago,so that's not it either.
After couple of days of my wife driving it,I noticed that the MIL always comes on when she starts the car after it was driven and the engine was hot or warmed up, so after a lot of searching and reading online forums,I came to conclusion that it must be the valves and it's"DE CARB" time.
Installed recirculating cc with PVC plate fills up with eng. oil 60mls. Rosstech shows no codes. Performance is An-ok. no oil consumption, boost gauge shows no vac. leak. We are at a loss. I noticed from the PVC system explanation that there is a check valve in the honeycomb insert in the oil pan to prevent eng. oil intake under high vac. If that valve fails could that cause my problem? With or without the cc there are no performance issues.
View 2 RepliesMisfire occurs at highway speed under acceleration, the service writer stated "we have to do a coil swap" meaning they just swap them from around, and this is the SECOND time they have done this, according to them this is how VW wants them to address this, now I understand factory procedures cuz I work for a Porsche dealer, but wouldn't you think second time around you would replace those things.
View 9 RepliesI have recently purchased a 2012 facelift Tiguan diesel and it has a running fault. When starting the engine, 50% of the time it starts fine, 50% of the time it starts with a "misfire" and sputters for a short while (5-6 seconds) then stalls. If you Rev it a bit while it is sputtering then it clears the sputter and doesn't stall. It doesn't matter if it's hot or cold. Once it's running fine then the misfire never returns until you shut off the engine and then try to restart. The start stop also fails to cut in and I'm wondering if this could be linked. It had a new battery and alternator fitted a few months ago but a non start stop battery was fitted. This has now been changed for the correct battery but both problems still persist.
View 2 RepliesI have a 2010 Tiguan and the check engine light has come on. When I use my ODB scan tool it doesn't find any codes and the check engine light won't go on. What might be the problem?
View 5 RepliesHave had our Tig for almost a week and it has stalled 5 different times. 4 times while in reverse and 1 time in drive. Took it to a local shop and no engine codes came up. Called my neighbor who is a Mercedes machanic and VW enthusiast, told him about it and he said something about additives being put in gas in the winter and it can cause them to stall. He told me to run a can of Sea Foam through my gas tank to see if that works. I also added some of the Sea Foam to my oil as well. Hopefully this solves the issue
View 8 RepliesI recently did a coil pack swap to determine if that was the cause for a cylinder 1 misfire. Left to right on my 2009 se tiguan, I changed 1 to 2, 2 to 1, 3 to 4 and 4 to 3. I recently ran into the cylinder misfire again, this time on cylinder 4. The problem is, I do not know which coil fires which cylinder. I've looked around quite a bit and can't seem to find it.
