At least 2 posibilities,throttle cable is sticking or binding or the butterfly shaft is sticking in ur carb.Take top off the aircleaner and spray carb cleaner or WD-40 on the shaft and see if that loosens it up.Also manually rotate the shaft where the cable attaches and be sure the cable runs free.Lube what u can see of the cable as well.Get up under the dash and be sure the accelerator linkage looks ok and is not stuck or binding.I wouldnt drive the truck till u get it fixed.BJ
