When you say the front AF sensor, you mean the front O2 sensor right? And when you cleaned it, did you use a brush or just a cloth? I haven't even looked at my MAF sensor yet, based on the error codes I posted before, I was told it wasn't my MAF. Here's all my symptoms:
-Real sluggish reaction...no get up and go.
-Check engine light with these codes: P0171, P0125 and P0135
Anything else to look at? Thanks.
