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
