I have a 94 Nissan Sentra and hve noticed that the car shakes way TOO MUCH when the car is warmed up. help!?

Question

When its cold it doesnt shake much but once its warm than almost immediatley it starts to shake as if it was a damn muscle car. I haven't done a tune up in a while now but before i do it does anyone know or have an idea of what might be wrong with the damn car. OH and also; the overdrive button doesnt work anymore and its always turned on. Sometimes the car turns off when i'm pulling out of the drive way in reverse and I turn the steering wheel without accelerating it. Stupid car pisses me off! I need help!

I would have wanted a more in-detailed answer but oh well. Thanks for trying.

Answer 1

The shaking is probably due to a manifold or vac *** leak or you desperately need a tune-up. Take the car to a do-it-yourself car wash and shampoo the engine compartment so that you can see things better. Then take a can of spray Gum-out, and spray around the air intake (throttle body) and around PCV hose. If there is a leak, the engine speed will change. Use your fingers to squeeze all visible vacuum hoses to make sure that they don't "squash" closed. This duplicates high pressure vacuum, like when you are accelerating. Check your fuse box for a fuse labeled transmission or overdrive. If you can't figure it out, go to a trans shop and have it checked out. There might be an electrical connection under the car that has worked itself loose. Good Luck!!!
