    then it is a bad iac. common on mustangs.

    to the other guy; yes it is fuel injected. fuel injection in mustangs started in 86.

    there probably is a vaccum leak. check by spraying some soapy water and listen and see for leaks and whistlings.

    is it fuel injected?

    if not it you need to unscrew the choke or play with it.
