Recently my 91 ford F 150 4 wheel drive was giving me troubles on acceleration. It would run all day long at idle and would run a whole tank of gas through it no problem perfect idol perfect running no problems. I replace distributor cap rotor button plugs plug wires and thought maybe this would straighten out the acceleration problem seeing how the truck I've been sitting for years when I bought it. Long story short in the end of everything after replacing numerous sensors the strainer bag in the fuel tank was stopped up. Problem solved. Hope this was helpful to anyone going through the same thing
