Searched for: The truck starts fine and idles, but when I give it throttle it does not speed up. It wants to die , it backfires or pops back up through the intake and barely runs. Return throttle back to idle and it runs good. I've put in a new distributer, tried two other throttle positioning sensor and a mass flow sensor, new spark plugs, fuel filter and fuel pump. What's next?!
