Any mods or codes? You can have codes without a CEL present.

Also post info about the truck (it has an AOD?).

That's how many of our cars surge - they idle great statically, but at a crawl (in gear with no gas application) we surge.

Good luck.

I am only getting a CEL code of 334 insufficient EGR flow and that's because I blocked off the EGR and my tranny is a E4OD 4x4 auto tranny so that's probably what's going on then...
