Having problems with your Pontiac Bonneville ?
My 1994 bonneville motor shakes when driving at 55 mph
\015 I just replaced the throttle control sensor and now when driving down the highway at 55 the motor shakes real bad at about 2000 rpm. Then I step on the gas and kicks it down a gear and is fine untill it goes back into overdrive then at 2000 rpm it does it again\015
