Default Idle issue

After driving a while and parked idling after 10 minutes rpm gets a little below 750 rpm then a little above.
I'm leaning toward some tb sensor but Idk. its sounded real bad after restarting it the first time.

750-800 when warmed up. Might be closer to 1000rpm when first started then decrease as it warms.
