Weird Vibration

MidNiteBlu 5.0 · 11-26-2002, 06:15 PM

well this just started this afternoon. this morning i drove to my 9am class and then came home the car was acting fine. Later i go to drive to my 2pm class and when i put it in gear and try to drive forward it starts vibrating alot. i never took it faster than 25mph or like 2500 rpms so im not sure if it is just a low speed vibration. At first i thought it was a flat tire but it isnt.

i checked all the spark plug wires and they are all fine. The engine does not vibrate irregurly if i just rev it in nuetral. Im thinking maybe its the U joints or driveshaft or something?

Also when i drive forward the shifter moves side to side fairly violently.

Help please

Thanks,
Nick

I wonder if your throwout bearing is starting to go bad. Is there any unusual noise coming from the transmission area???????

There is no noise coming from it. I am going to go check the motor mounts.

check both motor mounts, and tranny mounts, i know my car is about to rattle me out of my mind over 70 since my u-joints are shot.

Actually it is misfiring i just figured out. i never really got on it much until now and it is definantly missing. i have pretty new 9mm wires but i think my coil is stock and original. Im gonna check my wires and probably buy a new Crane Ps91 coil.
