I have seen this many times on this particular engine. What does it is; If you will remove the snorkel hose from the throttle body, and take a good look at the butterfly (that opens when you press the accelerator) on the inside you will see it has build up around the butterfly that causes it to stick, and it can't return all the way closed. They make some stuff called throttle body cleaner for this purpose. Pack a rag inside to keep the stuff from running down inside the engine, as this can do harm to the EGR valve and cause it to stick. Clean the throttle body real good with this cleaner while you operate the throttle by hand, and you will see it free up. This is all you need to do. Don't let the rags get down too far inside the throttle body, leave some sticking out in order to pull it all back out. This will resolve the problem.
Glad I could help you. Good Luck!!!

Most common problem with the Chevy truck motors, after time and wear, the throttle body butterfly bushings wear out causing the thrittle to get "sticky".
After the truck is running for a few minutes, the fuel acts as a lubricant freeing it up. The only repair for this is to replace the throttle body. due to the price, I (and most other people) just live with it.

You need to be sure that there is nothing causing the linkage to bind. It needs to move freely at all times. It could be that you have a broken engine mount, and the movement of the engine is causing the gas (throttle) linkage to not move freely, until the engine torque from the start up dissipates, allowing the engine to drop back against it's mount, and free the throttle linkage.

Disconnect the throttle cable from the throttle body, then check for ease of movement. Sometimes the cables deteriorate, and bind up inside the insulation. You can also check the linkage on the throttle body to see if it is sticky. A cable, or throttle body bushings are usually the culprit

I actually had that problem with a couple of the Chevy trucks and I sprayed WD40 on the pedals themselves and worked them back and forth. They stopped sticking.
