LT1 MAF Problem I just got my computer back from PCMForLess, car starts up fine, but idles a bit rough. The car is running lean, and once it reaches operating temp it starts to studder all through the RPM. I put a scanner to it, and I'm getting a P0100 code. I changed MAF, but still no luck. Just wondering if anyone has had this kind of problem before. Please give my your opinion on this issue.
hmm im not sure if this helps but i knew a guy who ram his car for months without a MAF, lol he ran directly off the TB, no filter no nothing, lol i tried to tell him, but the car still ran fine, MAF might not be the problem, lol well obviously its not the problem if u replaced it
but realisticly the MAF will not make the car not start, throw a pressure guage on the rail, than maybe look into an ICM or something of that nature that would couse a no spark condition. Im not saying you are not having a MAF problem i am only saying thats not why your car isnt running

I have a fuel pressure guage inside the car, reads just fine @ 45 psi with the vaccum off. The ICM has been replaced about 2 months ago and recently relocated to read a denser temp. The MAF not starting the car is not a big issue, since its never started without the MAF, even when it was stock. I've even check the MAF wiring and pigtail, and seem to been in good condition. I just rebuilt my stroker, and all sensors were replaced on this new engine.

check your fuses...I was pulling the same code for months and getting shitty gas mileage. changed the maf didn't work, the wiring...checked the fuse and that was the problem. it was keeping the maf, map and o2's from reading correctly
