#1 of 1 2007 Grand Prix Gt by packerfanjc Mar 20, 2009 (5:23 pm)
I have a 2007 grand prix gt and i have been noticing power loss. This car is supercharged. I used to be able to tell the power when i accelerated now it seams like the motor is working a lot more then it used to and the super charger is not kicking in. There is no check engine light on or anything. The car kind of shifts hard when you get on it and when you are idling it kind of surges so to speak you can feel it shake a bit. Anyone know what this might be or is this normal?
