Car jerking while driving at high or low speeds. I have replaced plugs, wires, rotor, cap, fuel and air filter. Transmission fluid level is correct.

Is the check engine light on? Have you checked fuel pump pressure?

It sounds like the engine is misfiring which will make the car jerk as mentioned, here is a guide on misfiring, I would do a compression test because this can be the problem.
