[QUOTE="ZombieHunter, post: 2197701, member: 5791"] How long since you have done a full tune-up? Electronic Ignition Module and and spark plugs and all wires associated? besides that, its very possible you have a phantom GM electrical Gremlin, which would have to be significant ie: A/C, Heater Core, Instrument Panel. Best bet is to do the full tune-up, then wipe your computer, have it factory reset, by either the dealership or a mom and pop shop if they have the capability. I remember my pop's 03' having generally the same issue, and he did full ignition tune-up, wiring harness, and any major system in the rig got an overhaul and new wiring or components. [/QUOTE]
