Sorry I did not clarify my statemant. "In gear" readings are still at idle with your foot on the brake--not driving. Check the readings and post back.

Your TPS is a bit high. I would adjust to.42-.45. Also your IAC counts are low. That 11 would be acceptable in park, but in gear it should move up to 30-50.

seeing as I've already cleaned it, should I replace IAC?

No, you need to adjust it. When you do it will move your TPS #'s, which is OK because they need to be adjusted anyway.

You adjust the IAC by turning the minimum idle screw on the side of the throttle linkage. If you turn the screw in it opens the throttle plate the IAC counts go down. If you turn the screw out, the throttle blade closes and the IAC counts go higher. After you achieve your acceptable IAC count, adjust your TPS to .42-.46 minimum and 4.80-4.95 max. If you swing by the shop or if I see you out on the way home.... I'll show you.. damn you are lucky .....

Stop kissing up! I can't stand any more. ( Just kidding ). Anyhow, you are very fortunate to have Jack at your service, and being how he has things under control, I'm signing off.
