Hello everyone, i'm new to the forums and new to the audi brand. When I start my car after its been sitting, it idles rough and won't accelerate when I hit the gas. If I shut off the key, and restart, its fine. Any ideas?
Its an 03 audi a4 Quattro 1.8t.

 

sounds like a coilpack. IF u can go to autozone or advance or any auto store and see if they can scan the car for trouble codes. Thats the best way to diagnose!
