While running cold everything is fine, but after the vehicle warms up it starts to run rough at idle and sometimes stall.

Start with the Idle air control, it's bolted to the throttlebody, then check for stuck egr, maybe even unplug an 02 sensor, it is affected only when warm, so since 02 and egr are out of the loop at cold start pay attention there.
