I still say there's an underlying MAF/leak problem here.
I'm trying to get see if I can barrow a MAF sensor locally before I spend money on it. In the meantime, I'm going to triple check my for a boost leak.
I also had a question about the CEL that shows up in Learning View. It is P0457 EVAP LEAK DETECTED (Fuel Cap). Would that error give me these problems? .. I'm pretty certain the fuel cap isn't loose, but maybe whatever is causing it is why the car is running lean?
