Can you explain a little more about what your bucking problem is. Is it when coasting, accelerating, cruising, what RPM range etc. Any CEL lights or other symptoms? Wild a$$ guesses would be plugs and/or wires, fuel filter, or possible fuel pump. (If bucking at higher rpms) If the idle and low speeds are rough, check for an intake leak.
No CEL lights, but the bucking does begin when I start to accelerate. It normally starts in all gears around 3k rpms. It happens whether I have a full or 1/4 tank of gas.
