I have a 2007 Grand Prix and tonight, when I accelerated on the highway the whole front end starting bouncing around and noticed the RPM's were staying around 1000 rpm's. what would cause that?
when I accelerate, the rpms go up, there is a strange sound coming from the car and then the RPM's go back down to 1000, I tried Cruise and the rpms still dropped on Cruise, any ideas?
Sounds like the transmission is slipping. Have you checked the transmission fluid level? Could be low. HTH. -Jim
