I have a 95 mustang Gt it has an high idle i just replaced the TPS and the IAC still high idle?
Also if i start the car with the iac unplugged it idles down some plug it up and the idle goes higher.

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.
