runs like a 2 cyl.
I have 91 f150 with 300 6 cyl. some time ago I had a new fuel filter,pump fuel pessure switch,both fuel relays plugs and spark plug wires put on it because it would not run at an idle then they said it was computer so they replaced that well the truck cranks and idles great now but wont run down the road.like i said it cranks and idles great .when you put it in gear its great as long as the motor is not pulling the truck .its running like it is only on 2 or 3 cylinders. i thought it needed to be run and it would be ok so i took her out for a 30 mile drive and the whole time it ran like that....ANY help would be welcomed....Bad Computer?????Thanks Danny
