so many of you know that i have been having problems with those codes on my truck. i was thinking it may be the maf due to the fact that if i unplug it the truck idles/runs normal yet when i plug it back in the truck will either stall or seriously studder, i was wondering if this may be a sign that the problem is my maf- Jay

 

have you cleaned it? do that the idler sensor and see if that helps.

 

yeah i cleaned it, wheres the idle sensor

 

on top of the trottle body. it has to bolts that hold it on.

 

Mine was a vacuum leak. Had a hose off. Once it was plugged in , I reset the pcm and haven't had that problem again. Going on 6 months now.
