[QUOTE="KingCobra07, post: 16040860, member: 138178"] Hey guys...looking for some guidance. Car is an 08 GT500, MMR shortblock, crower stage 3 cams, and a 4.0L blower. Had Lund (working with their new guy, Dakota) send me a startup tune, and car was running fine. We made it up to revision 5 to do WOT pulls, and something went wrong. On the first WOT pull, went foot to floor for all of 3rd gear, took my foot off the gas, hit 4th, and then the car suddenly died and wouldnt restart. We reloaded the tune, and still wouldnt start. Only crank. Checked all the fuses under the hood and found a blown one for one of the engine controls. Replaced it, car started up, but wouldnt idle. Goes into failsafe and gives me these 4 codes.... P0102 MAF curcuit A too low P0135 o2 heater curcuit P0155 o2 heater curcuit P1488 pvc heater control This is where Im at. Ive swapped the MAF sensor from a running car, but changes nothing. Is it possible my PCM fried? Ive reloaded the stock tune as well as previous revisions but it still comes out the same. Any input would be much appreciated. [/QUOTE]
