It sounds like the same problem I had with mine. Look under the battery at the motor/transmition mount. They are prone to break. Once that happens the rubber will ware.(The rubber is what tears out that's what you need to look at.) mine started at about 40000 was forced to change it out at 85000. Not recommended to run it like that it could bind the CV when the engine moves under load. And cause premature failure of the CV. The engine atleast mine didn't move by just reving the engine.
One of the possible causes of a Pontiac Bonneville to jerk during acceleration is that the car needs a tune up. The engine misfiring can lead it to jerk as you accelerate.
During acceleration? I'm not sure. But when both idling and acceleration the engine's combustion can cause a lot of vibration in the steering wheel if you are in an older vehicle.
Fuel Pump
It depends on if you have a carburetor or fuel injection but it is probably in the throttle body. You could have trash in your throttle body or the throttle body is worn out.
Bucking during acceleration can be caused by a low fuel level. When the car is running on fumes, it is not getting a constant supply of gas which will cause it to stop and go.
try changing plugs and wires
There are numerous issues that can cause a lack of power during acceleration. Common causes include a clogged fuel filter, a clogged air filter, and dirty fuel injectors.
A bad o2 sensor can cause this problem in a car. A bad fuel pump, fuel filter or fuel line will also cause hesitation during acceleration.
Driving at 50mph or above what causes a loud knocking clicking sound during acceleration?
Energy is released during fusion and fission.
Bad tire? Bad wheel bearing? Bent wheel? Bent axle?
