My car bucks a lot when I let go of the gas.
 

When Im driving my car and i let go the gas it bucks alot.Also I dont know if this problem is related but when my car is on not in gear it makes a whinning noise but when I push the clutch in It stops and when I let it go it makes the noise again. any help for these problems?

Any help :confused:

How hard? Like neck breaking or just a little bit?

in between

Could be the ignition system or the tps. Those would be my first guess. Does it miss at all while ur on the gas?

no it doesnt. do you think it could be fuel injectors

what do u think

I'd say start checking them one by one.

adjust your tps,.. thats usually at the core of bucking problems.

How slow are you going? In low gears and low speeds (around 20mph 1st or 2nd) the car will buck no matter what, that's just the nature of the motor. Yes, my TPS is set perfect :)

Got any extremely bad bearings on something? My car is so much easier to drive now that my alternator doesnt randomly steel 20hp.

Sounds like your pilot bearing is going bad.
Your bucking could be just a dash pot needing adjustment .

Wrong gear, the car will buck.

could also be an input shaft bearing but that is usually a grinding type of noise when that bearing goes out, a hum or whine is usually a pilot bearing.

I don't think that's what he meant.
