SOMEONE HELP!!!!!!! lol seriously
so my 1989 ford ranger 2.9 v6, it will not keep its power to it, it would lose power at about 4000rpms and bog down a lot when im on flat ground but when going up hills its loses power at 2000rpms since giving it more gas for the hill i guess so.......i basically gave it a tune up replacing the spark plus , wires, distributor cap, and oil change, distributor module and it still does the same thing. what could be causing this?!
