My 4.6 is throwing codes for too lean. I am going to clean the MAF sensor as a first step, but the sensor itself didn't fit too well when I put it back in after a CAI upgrade (it was a demolet CAI). Does anyone have any ideas on how to get the sensor to seal better? I think the stock part it went into was flat, at least it was flatter, the part now is round and I am having a hard time getting it to seal right.
thanks
