MY 96 f150 195k is driving me insane. For example the other day I started it up cold and drove the truck for ½ hour stopping for an hour and restarting. It drove fine. Lot’s of power. I drove around for an hour, stopped to photo engine components for reference and left it idling. Within 5 minutes the idle dropped and it ran rough. Had very little power even to rev the engine. Pulled the Mass Air Flow MAF sensor wire and idle returned to almost normal had power but probably not 100%. At one point it almost stalled. Put MAF back on and it drove like new again? Benn driving it like this for a month. Thanks for any help. I’m out of hair.
