Well, I cleaned the MAF and hooked everything back up and the CEL light came on again. What else can I start looking at? Could the EGR valve be stuck open or something? I didn't physically hear any vacuum leaks or anything so I am not sure if that is the problem. The guy that I bought the car from said he was told he needed an o2 sensor, but with the codes saying that banks 1 and 2 are running rich I would think that rules out the o2's because normally if it was running lean that could be a problem.
So anyway, what else can I do to try and track down the problem. Thanks for the help so far
