sounds like you have carbon build up, on the butterfly vavle of your throttle body. Remove the air tube and look inside the throttle body, move the valve open and closed by hand. If you see carbon biuld up clean with a can of throttle body cleaner and a small brush. reassemble the air tube and start the truck let idle a minute to clear out the cleaner. Should take care of your problem.
