Clean the throttle body and idle air control the best way is to pull it off spray/soak it with carb cleaner and blast it good with the hose. Make sure you get a new throttle body gasket to put it back together first. It will probably just help to clean around the butterfly and the IAC might be sticking but I would start there.

My credo
The memories of a man in his old age are the deeds of a man in his prime
Does it restart without problems?

Mine does that when it is cold, it lives outside.

Pull codes to see if it has a registrable issue.
