Sometimes that code is generated when the charging voltage from the charging circuit is too low and the minimum airflow spec gets lost by the pcm. This can be a bad alternator, battery etc. As well if someone has adjusted the set screw in the throttle body trying to fix the code then I'd suggest retesting with a used throttle body. As well one last thing the intake gaskets/plenum pan on those engines blow out and cause a vaccum leak that can cause spark knock and oil consumption. If that vaccum leak was large enough it could cause your low vaccum reading and that code. As always check the accuracy of the map sensor and tps when dealing with idle speed issues

After the IAC is replaced it is not enough to clear the code you must also reset the IAC learned adaptive. To do this you will need a higher end scanner like snap-on or such.
