90 f150
i have a f150 with a 5.0 engine after it warms up it acts like no fuel is
getting to the thottle body but it will still idle rough. if you let it
cool down for 5 to 10 min. then it will run fine until it warms up. what
can cause this if vapor lock only occured with fuel pumps on the engine
and not in the tank ?
