I have a 1989 f 150with a 300sixceylinder motor lost power slowly it idols but if I give it gas it boggs down
This is my moms truck its
our only transpotation im
fifteen year old but I think
I c as n fix it if you will tell
it could be trash in the throttle body. but most likely the fuel filter, which is located under the truck on the frame or under the hood. depending on who has messed with it. if not that try picking up some carburetor cleaner of sea foam at the auto store of walmart, and spray it into the throttle body. not sure if thats it but from my experience with this problem it has always seemed to fix the problem for me.
also check air filter could be starving for air
