What does the Idle Air Adjustment plate do exactly???

It allows you to adjust the amount of air that bypasses the TPS. It allows you to allow more air past the closed TB during idle. So if your car is surging at idle, sometimes you can allow more air to bypass the TB to calm it down.
However, they should really call it a band-aid, because it doesn't fix anything. All it does is cover up the problem that is causing the surging idle in the first place. It is no different than just upping the idle screw.

I bought one of those things, didn't do much of anything. Except remind me that the problem was really that I need to get a PMS tuner to get the thing to idle right. Usually its just a vacuum leak though that causes surging.
