Hi .

Tony this sounds like a typical throttle body and IAC valve that is dirty and needs cleaning .

First remove the throttle body and clean this with a carb/injection cleaner spray can.
make sure you clean all the bores good with a old tooth brush .

If you still have issue after the clean out then please get back to me .

Kind regards Greg
