hey guys im having a little bit of a problem here. the truck still idles fine but as i acclerate, it seems to only accelerate in increments like its short on fuel for a second and then it gets it and then repeats that process. eventually it levels out and is ok once it gets up around 2,000-2,500 rpm but its just strange. ive asked around and msot people seem to think it has to do with fuel delivery and more specifically a fuel pump on its way out or possibly a clogged fuel filter. any suggestions on where to start?
