Just went through all of this crap TWICE!
Than on the way home from Moab it decided to bog down and kill the engine (on Vail Pass). Called OffStar and they said it had to do with my PCM had thrown four codes. Offstar rep told me I "may have reduced engine power." No ****? I couldn't even push the gas pedal down to get it to hold at 1500 rpm without the engine killing. So we loosened the gas cap, pulled the two PCM fuses, tried to start the truck, put them back in, and made it home. Hummer Roadside picked it up today with a flatbed. At only 4500 miles and this being the third time I have had "Emissions Issues" I really hope they get it fixed this time and soon. I have five days worth of Moab dust to clean off/ out of that thing.
