So, this showed up this last weekend... P2097 Post catalytic fuel trim too rich bank 1 Fuel Sys 1 CL Fuel Sys 2 NA CalcLOAD % 41.1 ECT(°F) 201 STFT B1 (%) -.7 LTFT B1 (%) -.7 MAP (inHg) 13.8 Veh Speed MPH 64 So, the code has a long list of things that could fix this. I but a CAI and cat-back exhaust on in the last month. Could it be just the O2 sensor or something worse? If it is too rich, I really don't want unburned fuel going through my catalytic converter causing it die sooner than it should or sitting in the new exhaust. Any ideas on what to do?
