Yes you can, but often with out much success, but it is worth a try, use a good quality throttle body cleaner and see how it works.

This is probably a faulty IAC valve, try a clean first and run a scan for any unresolved fault codes.

No, do not bother with used units if faulty, I do believe that larger parts stores there may do free scans, try pep boys.
