I've had my Grand Prix Comp G GTP for a year and a 1/2 now.

GR8 car!!! I have a question though on cold starts. I just got it back from it's 3 month check up and the tech cleared some codes out of the computer. Isn't there an update if codes are found to fix this?

Still having a hard time starting the car in the morning. And when I back out of the driveway the car chugs and then wants to stall. Some times it does. Some times I get a power surge and the car lurches ahead without my foot on the pedal.

Gotta love Central New York. Any ideas out there? Thanks!
