Having problems with your 1999 Pontiac Bonneville ?
1999 pontiac bonn vibrates violently on take-off
Motor mount loose or off,,,,,bad rotors on front brakes,,,,,rotate and blalance tires
Is this a manual tranny or an automatic? I'm guessing an automatic. If thats the case what you are feeling is worn clutches in the tranny. or a badly worn pilot bushing, 'i can only assume you tend to hammer the throttle a bit correct? Why not it's a boss car.However these problems will raise their ugly heads on occasion. Good luck, Dana
