Options for Idle Air Bypass Valve Replacement

My bird is starting to do the signature sign of a failing idle air control valve where the car idles at 2000 rpm under certain conditions. After checking other potential causes (idle screw, tps, VAM, vacuum leaks) and attempting to clean the valve with brake clean, I have decided that a new idle air bypass valve is needed. The factory part is no longer in production so I ask this question of you fine folks:

1. Is there any way to rebuild the IAC?

2. Do you have any recommendations for a new IAC?

Stock. I finally got it to work correctly. There was a ton of corrosion where the wire connects to the connector on the harness side. I couldn't remove it or see it without disassembling the connector.
Good reason to always check things with a multimeter as taught in avionics repair class.

Corrosion on the plug on the IAC was the issue? Curious, I have had similar idle problems and had ruled out the IAC despite the issue remaining...
