I will give you this much.... It has to do with the new MAP sensors they put on it. It's in the very first post from the solstice forum if you use the google search line in the upper right corner.
HINT: DO NOT let them charge to fix the code!! If you would have had someone send you the tune, you could have bought the plugs for the sensors...instead the dealer has "crimped" them, which means in 2 years, you're going to have to solder the wires.....Or you call the dealer and have them solder the wires.
