You can adjust the idle air control valve on a 1992 1500 truck while it is just idling. This is done if the truck is idling too fast or too slow. It will help the truck run better.
It's not a part, there are parts... First of ECU, then EGR valve, idle control valve, MAP sensor, oxygen sensor.

You don't. The ecm adjusts it.
Remove the EGR valve from the Corsa. Wash the EGR valve with carburetor cleaner. Make sure that the valve is clean of gunk and let it dry. Reinstall the valve.
