I had replaced my air filter a few days ago with a MANN filter from amazon. perfect fit and no problems installing it. Could I have done something during the install? Would a non OEM filter trigger any problems? I'm thinking of trying to clean the MAF sensor first with a MAF cleaner. If that doesn't work should I try replacing the MAF? Or am I completely off and the problem is with an O2 sensor or something else. Any help or thoughts would be appreciated.
THanks.
