...are you saying you replaced the MAF to no avail? If so im really sorry to hear that. Its just that every problem you have mimiced mine in every way. Maybee at this point it may be time for an indepth diagnostic from the dealer...but if you have allready done one than im stumped too. One last thing i can say is that about 3 months ago i started getting a misfire, and the check engine light flashed frequently, i thought i was getting a bad MAF again. When i took a closer look I found 2 plug wires fraying on an almost soft metalic coated heat shield on the passanger side near the coolant tank. Check and recheck your wires for grounding or fraying. But since you said you replaced your plug wires i dont think that can be relavent. I hope you figure out whats wrong because i remember the headache i had trying to figure out my problem. I sympathize with you though.

I know it sounds stupid .but have ya checked to see if one of the wires have fallen and is laying on the exhaust?Also take the cover off where it says vortec and the little black round thing in the middle of ur intake.Look down in there to see if there are some real clean places.Like where guess might be leaking. Aslo called washout.you may have an injector,or your presssure regulator maybe leaking.Or maybe your regulator isnt adjusting for the decrease in speed and rpm?i dunno might be worth looking into.

Hey

I hate to bring this up again guys, some of you are probably getting sick of hearing me talk about the ignition control module, but really sounds like it to me, and its a fairly cheap part to replace. my truck always ran nice, then would heat up 15-20 in my commute, and start getting a misfire.
