If you are having no issues other than this then I would first look for any vacuum leaks. Check all of the vacuum hoses good as the age of the truck says this could be a problem. If something found, fix it before continuing. These trucks had tendency to have the throttle body gasket split and move which can cause stalling or high idle. To find this for sure, buy some type of a pressurized cleaner and while the motor is running, spray this stuff around the base of the TBI and the intake where it bolts onto. If you notice the motor start to stumble or rev up, remove the TBI unit and replace the gasket. If that isn't the problem, you might have an IAC motor faulty or something telling the PCM to drive the motor out to account for some type of load. Good luck.

At this point with your car being almost 15 years old, the most trusted place would be a Chevy Dealership/Repair location. Fifteen year-old parts are difficult to find, but Chevy undoubtedly have records to see which parts changed or have been renamed.
Don't mind me for what I'm about to ask:
Unless you are a race car driver (500 to 150000 rpm) why are you keeping the pickup? I know Chevys are BUILT LIKE A ROCK, but even rocks crumble within time. Over the next few years more and more major repairs will beckon your wallet

If chevy engines blow up at 90K, i need to tell my 94 1500 to blow up-it has 240k on it, and theres nothing wrong with it.

A new engine. Chevy engines are due for replacement at 90K anyway, yours could blow up at any second.

Your I.A.C. motor is either carboned up or failing. I.A.C. stands for idle air control.
