Try cleaning the Idle Air Control Motor. Also clean out around the butterfly in the throttle bore with carb cleaner and a rag. This should help stabilize the idle. That truck shoul dbe "drive by wire" ie, no throttle cable, if so then it doesnt have an idle air control valve which means you may have to replace the throttle bore to fix the problem, but try cleaning it first
