missfire

had this problem for a while now. Basically under load I get what sounds like a single cylinder miss fire, the car also won't hold boost and will start to drop at around 5k. I also had the engine management light flash on and off for half a minute. I think this could be down to a spark...

Hi, my 1.8T which has been remapped has an annoying issue. it hasnt always done this pre or post map. in 3rd it sometimes misses at 6krpm, but you can drive through it. also, under part load the car hesitates, but is fine at WOT. does the same with an N75F and N75J. any thoughts?

As title says. only does it from cold and in cold weather (about 0-5 degrees) It doesnt happen all the time though and its not especially bad (compared to when it was running of 3 and occasionaly 4 cylinders when a ignition lead broke). Spark plugs where replaced about 4500 miles ago. thanks

Had a few missfires the last couple of days only under load while booting it, VAGCOM shows no codes. Coilpacks and plugs seem ok but what i found odd was that unplugging the MAF seems to cure the problem (and makes the car a little faster). So i'm presuming the MAF is screwed (again), could the...

Just thought I'd leave a quick message about the problems I've had with my V5 and what I did to fix it, just in case anybody else has the same frustrating problem as I did For about 3 or 4 months the performance on my car had been deteriorating on an intermittent basis, especially on up...

I have done a search but cant find what i am looking for... I have a what seems to be a missfire on full bost, I have revo stage 1 and the car runs fine, I am running 21psi and was fine for a few months after i brought it. I have changed all the coilpacks and the spark plugs, so i have been...

hi, my gti has an intermittent missfire sometimes the car starts up fine and drives really well :) and other times it will start up, but if i try to pull away or accellerate it will bog down and missfire alot. This can be really embarrasing because it sounds terrible and its really...

Hi Leon owners, Got a small problem with my Leon Cupra, 51 plate. When started from cold, it will miss fire for a few seconds on and off and then as soon as the secondary air fan cuts off it will be perfect, no problems when hot or when driving on the road. There are no faults stored in...
