In many cases the issue is with an out of balance tire, you can have them all balanced fairly cheaply and a rotation is probably in order, I believe it's all in the same price, after that the alignment could be the cause, if the wheels are not straight forward they will shake, and newer cars need 4 wheel alignment, after that it could be your engine timing or a bad engine support.,
It could be your bushings.
Your car probably has abnormally worn in tires, caused by misalignment. Worn rotors can cause this as well.
i have a 1991 nissan sentra speed up to 35 and start to miss
Perhaps spark plug wire got disconnected in error?
You probably need to get your tires balanced. Or replaced. If the bias goes (steel belt breaks or shifts), the car will waddle at low speeds, and the steering wheel will shake at high speeds.
== == As the car speeds up the unbalanced wheels start to wobble. The force of the wobble is transferred to the cars body through the steering mechanism. You would feel the shaking first in the steering wheel. It becomes more pronounced as you pick up speed. == == * Front end need's religning, bad tires or tie-rods. * Tires are low in air.
No, not unless it is so low the engine is overheating.
prob a broken belt in one of the front tires
Have you tried having the wheels balanced ?
My 92 PA had a similar problem. At low engine speeds it would shake pretty bad. It turned out to be the harmonic balancer. You can easily check this by looking at the front end of the engine. It is the pulley that drives all the belts. If the rubber has deteriorated, it could be the cause of your problem.
it most likely is an oxygen sensor
not downshifting.
Squeking at low speeds? Its your coil springs in your suspension. Have them fixed and the problem should be solved.
