When you replaced the MAF did you also replace the PCV?

Well, if it were mine I would probably go ahead and replace the other coil packs just to be sure that you did not have more than one fouling. I don't know for sure, but I once heard that a throttle position sensor has to be calibrated. It is not a plug and play sensor.
