There should be more than 1 vacumn hose.
Remove the air intake hose, do not disconnect IAT or any other sensors.
Start engine, at lower part of throttle body you would the IAC, disconnect it. Does the engine rpm goes up and hunts? Plug the socket back, does the rpm drop to 700?
If yes to the above, the IAC is ok.
