Throwing Codes Hello everyone. I'm throwing some codes and was hoping you guys could help me out. I have a 2002 s4 with APR Bi-Pipe, Hyperboost Diverter Valves, AWE s-flo intake, APR chip, custom 3" cat back and a level 10 transmission. I'm throwing the codes listed below. I know that it could be a dirty MAF or an O2 sensor etc. My question is with the codes I have listed does it narrow down my problem? Any information would be great. Thanks!
