I have a 96 Dodge 1500. When going up hill the truck looses power. I can mash the gas peddle to the floor and the truck will not gain speed. At most it will hold the speed around 60mph.
I have replaced the plugs, plug wires, the PCV valve, the air filter, the distributor and rotor. No change in the problem. I noticed a little bit of oil on the air filter I changed out. Any suggestions on what needs to happen so I can actually pass a car if I need too or go up a hill without coming to a near stop unless the peddle is all the way down?
