    Try cleaning it first.I always used brake cleaner and some clean
    towels.If that doesn't work your IAC could have failed and mite
    need to be replaced.

    Yes, I recommend you replace your IAC gasket too.

    If cleaning the IAC didn't fix it, try cleaning the
    throttle body where the throttle plate meets the housing.
    Don't use a harsh cleaner here, just wipe it down
    with a shop rag and windex or simple green.

    . . .... Must be either a Northerner or an Ol' Timer cause I thought I was the only one who searches every new store for SG. Good stuff and biodegradable.

    ---On topic now, that is one of the only things I haven't done to mine and it'd probably do some good for that maximum 23mpg I am yielding. FWIW, if both surfaces are true and clearance isn't an issue, I'll use Indian Head Gasket Maker (AKA Indian Head Shellacking Compound or Old No.9).
