My 04 Pontiac Grand Prix GTP Supercharge is having engine trouble, so I think! Drove to Virginia from Indiana about a 10 hr. drive, well in VA. there was a lot of mountains where cruise control would turn off on it's own(which no longer works), then would heat up. Now when I turn on the car the motor shake alot and sound as if it wants to turn off with a funny smell from muffler and when accelerating on gas it putters alot, then braking will try to turn off. Can someone help me with these issues???

P.S. I did disconnet the negative wire from battery for about 6 to 7 hrs, still same results...

There could be numerous causes for these symptoms ..you need to have your cars computer read for any fault codes .. most good autoparts stores do this for free .. please have the vehicle read and get back to us with the codes for more assistance ??
