Does only happen at idle or running down the highway? With intermittent issues, you have to test when problem is ongoing or it's tough to find.

If idle issue, I clean the throttle body and idle air system. Other idle issues, check for a leak of some kind, fuel--egr--vacuum leak, of course it may only happen intermittently? How long since a tune-up? Any applicable trouble codes?
