Having problems with your 1989 Ford F 150 ?
I have low fuel pressure when you put a load on it and it wants to backfire and bog down on a ford f150
Try replacing your fuel filter, it may be constricted. Do a tune up if you haven't done a tune up in a while. check your spark plug wires to make sure they're not arcing(do this at night with no light), start her up and see if the wires are not arcing current to the engine block, if so replace.
