You need to clean your throttle body thoroughly. It's probably sticking open slightly. Pull it off, take any sensors off it, then hose it down with carb cleaner and scrub any hard to reach places with a tooth brush. Reinstall it and try again. If it still has the problem, add another throttle return spring. Your stock one may be worn out.

what LS1Formulation said pretty much hits it on the head, my throttle spring actually broke after I primed the truck. Cranked it up and it revved to like 6,000 lol prolly not to good.
