Yesterday i took my car out for a long drive (350miles).

On the way back it started misfiring at +15 PSI.. after a while it was over..
20 minutes later it came back and a lot more, if i boost it feels like i have misfires on all 4 cilinders and it feels like the RPM/REV limiter comes in..

Spark plugs almost new, no codes with VAG-COM... Tomorrow i`m organising a reallt big meeting, so i really like to have it working....[:(]

I cant find out what it is, can anyone PLEASE help me...? I already send UPS to the other side of my country to pick up the f*cking expensive ICM
at a big Audi specialist, but i`m not sure is is the ICM...

I have no idea, they came out of the box and right in to my car...

Can you recommend me anything...?

Swapped the ICM and coilpacks, runs a lot better, but now it feels like i`m driving with the handbrake on...

The Company made a mistake, i payed $350,- for brake discs 300x22, 4 coilpacks and the ICM...

What type of plugs? You might want to pull them out because most plugs will have a large gap so that you can set the gap smaller to what you want them at which would be around .032

Can A MOD merge the topics, something went wrong, sorry...

@Mike: I dont feel any misfires right now, but it feels now like something is holding him back, maybe misfires on high rpm..

Do i need to upgrade my coilpacks..? I didnt dyno yet with new software i think its around 350 at the crank...

Do you have a vagcom? If so you might want to log the car and see if you can get it to happen.
