At the moment I am having a few issues. When I start the truck it runs fine. When I rev up the engine and let off the gas the RPM's drop quickly, but once the engine warms up to operating temperature when I rev the engine it is slow to return to idle. It does return though.

Any ideas?

I want to get everything in order before I have to take it to the referree station to get my new VIN sticker.

You may want to clean and reset IAC. If you search through this thread there is a set of instructions how to do that. The other suspects can be flaky TPS - or sticky throttle. Also double check that you CTS is reporting correct temperature.

Before going to referee station make sure that you have ALDL connector wired and bolted, as well functional SES light.

Good luck
