95 Olds 88. "jerking" during acceleration

[Fester5150]

My mom has a 95 Olds eighty eight. Car jerks while accelerating. Changed plugs and wires, no help. Took to a mechanic he said the motor mounts are bad. I asked him how would that make the car jerk.... he said during acceleration, the motor turns and since there are bad motor mounts the engine is moving more than it should and is pulling on some electrical mechanisms which is causing a bad connection/loose wiring, etc. Replacing motor mounts tomorrow. We will see if it works. Hope this helps. Any suggestions/comments to this post telling me the motor mount solution is not the problem, it would also be appreciated! Thanks

Well..... I bought the "three" motor mounts. Took the parts/car to my mechanic friend to help out with the repairs and he was really against the idea that it was a motormount problem!! So needless to say, we didnt change the "three" motor mounts. We did check all "three" mounts and they looked good. We changed the cam shaft sensor, and fixed a couple of vacuum leaks. Ran 10x better but did not fix the "jerking" problem. While under the car I did notice a fourth motor mount that looks like a dog bone on the passenger side (underneath the firewall). The rubber bushings were shot!!! While returning the motormounts to Auto Zone, there was a guy replacing a battery on a 94 Olds 88. I ran down the problem to him and mentioned the motor mount solution and without hesitation said that was the problem!! Any advice before I waste more time and money would be appreciated!!!!

Any bad mount can cause a thud or thump when first taking off, on decel or shifting to reverse, this is not what you are describing.
