I know this post is old but I though tI would see if anyone could help me out. I have the same bucking problem, always when at 1/4 tank or less. Usually it is when I go to step on it she starts bucking like crazy and has almost got me killed when trying to pass on a 2 lane hiway. Thing is I had the fuel pump and sock filter replaced like 10K ago and the fuel filter, plugs and wires replaced all this summer. Do you think it could be a bad pump again? I bought it from auto zone and Had to pay to get it installed because I am at college and have to tools or equipment to work with. I swear Ford cannot make a reliable car if its life depended on it, but somehow I still love my car.
