    Can't get up to speed without the rpm's spiking or truck shaking. Just started happening. Loss of horsepower. The transmission and differentials are full of oil. Any suggestions would be appreciated.

    You do realize that a bit more info on the truck would be needed, don't you? My first thought would be an injector not firing.

    is there any other indicator I can look for to know if it's a fuel injector.
    When I get up to speed. Doesn't matter what gear I'm in the rpm's will jump and I loose speed.

    !st. change fuel filter an pour out old filter to look for water or dirt in the fuel that pours out of it? If theRPM of eng are rising and road speed is slower with eng. hitting gov. its the clutch slipping you should smell it burning?

    Take the truck to the dealer and have them look at it. It is hard to diagnose something when there can be a number of things causing the problem.
