Hello, thanks for posting

A low idle can be caused by a lot of carbon and gunk deposits in the throttle body, try having the throttle body cleaned or do it yourself with a can of throttle body cleaner and a stiff brush, open the throttle plate and clean all that carbon out, do this with the battery disconnected, after that rive it for about 15 minutes and the idle should go back to normal.
