This a turbo or none turbo engine? If this is a turbo then your PCV system needs to be cleaned out along with the throttle body. This should take are of the problem. Worse case scenario you would need a new throttle body and those are expensive since they need to be programmed to the vehicle. Start with the clean and let me know what happens?
