1990 Ford Bronco II won't go over 35 full throttle, but we jacked the rear up and it ran fine.
Replaced fuel pump and fuel filter. Began when i would go up a hill and the
truck would lose power. Later the truck failed to go over 35 mph with the pedal
to the floor. We jacked the rear up and it ran fine and as we dropped it, the truck
lost power again
