I had the same problem and the dealership said there was a small vacuum leak. They found the problem was a failed "Vapor Management Valve". Maybe it's the EGR valve? They had to remove the passengers side fender well to replace it which was done under warranty. Problem Solved. Been about two months now with no reoccourance. The part they replaced was only $21.48 #SPO F8ZZ 9C915 CA. Hope that helps.
