I would take off the throttle body and give it a complete tear down and cleaning. Also replace you IAC valve. Here is an instructional video. https://www.youtube.com/watch?v=2a77eCwb5Zo If no change in performance, have error codes read. You may have a bad crank sensor or dirty or bad MAF.

There's a sensor that sits on the intake that dumps fuel for when you first start your truck and its cold it dumps a lot more but doesn't register when motor is hot so keeps dumping same amount of gas as when its cold had a 97 GMC sierra same thing happened
