I am having trouble trying to figure out why I don?t have any power. the truck will start and run, I can put into drive and drive it down the road. When I push the pedal to the floor, the engine will bogg down. When climbing a hill and extra power is needed to climb it, the motor boggs down. In attempted to repair the problem, I have done a complete tuneup(plugs, wires, cap, rotor), replaced the distributor. I also replaced the gas tank due to minor leaks and a pressure gas line.
Any advice would be appreciated.
