Answer
I suggest that you have the throttle body cleaned as well as the idle air control valve and its corresponding passages. You may also want to check the EGR valve for a possible blockage or carbon build up that may be causing it to stick. Verifying the Mass Airflow Sensor is within range with a scan tool when it acts up may also reveal a bad MAF or MAT sensor that is causing it to enrich the mixture when it is already warmed up.
