Could be LOTS of things...best if you can get codes 1st then move on...save big $$$ when getting parts

With an increase in RPMs and decrease in acceleration, the first thing that comes to mind is brakes. You might inspect and make sure you don't have a stuck caliper or something (jack up the truck a wheel at a time and turn them by hand, they should turn freely).

+1 to pulling codes, but is there anything different about the way the engine runs? eg, idle the same, sound different, etc?
