When running the A.C. or heater my 03GT runs at about 1700 R.P.M., it will drop down to a proper idle speed after a while, sometimes it runs perfect. It doesn't do this with the A.C. or heater off. I replaced the idle control valve yesterday but that didn't help. What do I check next?

idk check the T/b see if its closing all the way or sticking. Is there a vacuum leak somewhere.

Also, disconnect the battery for 5-7 minutes to clear the KAM and let the PCM relearn the idale air trim. You need to do this anytime you alter or change intake or fuel system components.

Thanks for the help.
