Check your idle air system and clean the throttle-body. Also, a leak of some kind can cause idle issues, fuel--egr--vacuum leak, something like that.

How long since a tune-up? Are there any applicable trouble codes? Some of the national brand auto stores will check codes for free.

Just to add, not much load on the engine in park or neutral.
