  1. engine stops accelerating and just idles while driving

    4.2L V6 Specific Topics
    OK, so just recently my 03 f150 sport 2x4 V6 has had a funny problem. While driving, suddenly it will go right to idle rpm and I will have no response in the gas pedal, until I let off and re-apply, and that only works sometimes. I replaced the fuel filter hoping that might have been the issue...
