Okay well I was driving back to work yesterday and my car started misfiring like crazy, completely undrivable. Anyway I pull codes on it, turns out to be Cyl1 is misfiring, so I went and bought new plugs put them in, still nothing. Switched coil pack from cyl 2 to cyl 1, still nothing, cyl 1 was misfiring.. Switched injectors from the rail from cyl2 to cyl1, still cyl1 is misfiring.. The entire head was completely replaced by Audi in May this year, so it can't be a burn't valve... Crappy fuel, was thinkin about it but I fill up at the same place all the time and have no issues, ever.. Donno when the last time the fuel filter was replaced, car is at 117k.. Donno the last time it was ever seafoamed either..

However now I am leaning more towards the ICM, what do you guys think?

http://www.ecstuning.com/Audi-B5_A4-...Module/ES1723/, I could just buy that slap it on and see if it works.. Any thoughts on this? need help asap!
