Q: Engine stutters under load in high gear.

asked by on February 09, 2017

My 1997 F250 7.5L (460) gasoline engine stutters when pulling hills (or under load) in high gear. This is the 5-speed manual transmission 4x4 HD model. There is no change in engine sound, just a hitch that can be felt. I have replaced the distributor cap, rotor, wires, and plugs as well as the fuel filter. Any suggestions?

My car has 102000 miles.
My car has a manual transmission.
