Intermittent Rough idle - 2010 Exp EL 4WD - with video

[rrvolfan]

Need help identifying this issue. 2010 Ford Expedition EL 4WD. 33,000 miles. This problem happens intermittently when idling. Example, it will happen sometimes when sitting in a drive-thru line. It happens 2 - 4 times a week. The symptoms stop when you shift into neutral and rev the motor or if you pull out. Motor oil changed every 3000 miles, synthetic. Other than this issue the vehicle runs great. When I take it to Ford to diagnose, they can not replicate the issue. Neither can I, as it happens very infrequently. However, I did capture this on video hoping someone can help me out.

I uploaded 2 Videos to youtube showing the issue:
