Whats up everyone, my name is Andy and I am new to this forum. I have a 2006 A4 2.0t and it just started miss firing for a reason that I do not know. I had it scanned and code came up miss fire cylinder 1. I changed out all the spark plugs and ignition coils and no luck. I do not know where to go from here. When I start the car it start fine and there is no problem. If I have the car parked and rev the engine there is no problem, but when I am in drive and I accelerate that is when it begins to act up. Its usually at about 2000+ RPM once I am done accelerating and at a stable speed and just driving along there is no problem. The problem is only on acceleration. Someone please help.

Thanks, ANDY
