Iac reset is different than stock. I did this on accident, before i read this procedure:
1. Remove battery power for one (1) minute. Restore battery power and place air conditioning controls (if equipped) in the "off" position.
2. Firmly apply the parking brake and block the drive wheels. Start the engine, shift the transmission to drive for automatics and neutral for manuals.
3. Allow the engine to run until the engine cooling fan has cycled once, or a maximum of 10 minutes.
4. Turn the ignition key to the "off" position for at least 5 seconds.
5. Repeat Step 2.
6. Allow the engine to run for at least five (5) minutes.
The correct IACV values for proper idle control will now be stored.
