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

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

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 .

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.
