If you can beat RockAuto'* $25 (including shipping), PM me and let me know. My old one is working again, but who knows when it'll die next time.

Sorry, false alarm. The parts aren't interchangeable.

HI..my shop manual says,, to check and set the iac valve....
turn key to on,, do not start,,,ground out a and b on the connector under the steering wheel, or on the diagnostics connector, and let it sit for 30 seconds or more.....then disconnect the iac valve, remove the grounds from a and b and start the car...see if it idles right after this,, turn car off and reconnect iac, drive car over 40 mph which will reset the computer and the iac will then be set correctly...

Kenny
