Mine does this too from time to time, usually after i go over something rough and the truck bumps enough, it wll rev up to 2500-3000 rpms or so and want to hold it, after a few seconds of driving it seems to calm down though, never really looked into it, but it would be good to know in case its no bueno.

Try cleaning your IAC (Idle Air Control) motor, Its a silver thing on your intake plenum . Its held in by 2 - 8mm bolts. it controls extra airflow into intake so engine will idle, There is a little valve and a spring and its probably full of grime and carbon. Take some carb cleaner or brake clean and clean it out, and make sure the bit inside moves back and forth freely. if not replace it.
