Need help diagnosing P0171 2.0T Rough Idle
Hello everyone, my A4 B7 idles rough, I pulled the code P0171, the car has only 59k. Do you guys know what could be the problem? Is it the PCV or Maf sensor? Or could it be a vacuum leak? Where should I start looking?
By the way, coils are new, as well as the spark plugs.
