okay, I did not think it would be fuel unless its getting to much. It runs great it idles smooth and I can drive it but got to take off slow if I push the pedal to hard it just bogs down really bad or if you rev it, but I can rev it up if I just push lightly. it looks to have a new fuel filter in it and the pump don't seem to be making much noise, Someone had suggested the throttle positing sensor would that cause this??
