Before replacing the IAC I gave the throttle body and the inlet where IAC site a good clean with throttle body cleaner. Cleaned all the edges of the butterfly. Wasn't sticking and creating a good deal from what I saw

NJ said the air bypass may have been adjusted.
That a different name for the “idle screw” adjustment?
Either way, could be a likely culprit. Sorry I don’t know how to set this thing correctly.

No, different to the idle screw that opens butterfly further. Technically shouldn't touch the idle screw on efi. This one is down in a hole in the throttle body that is in line with the butterfly and is just a needle that allows a certain amount of air past it at all times. Takes a Philips head screw driver

Question

Hello guys! image attached is from the half part of the throttle body of a 6g72 sohc engine. This is where you find the idle up servo. my question is . . . has any of you have an idea on the use of the some sort of a thermostat? does it only control coolant flow or air as well? since it has chambers where in only air can pass through and tubes where only water can pass through. is this also a sort of and idle up when started cold?

There doesn't seem to be any thermostat in there. The water seems to just be warming it up, and the separate air ports are where the IAC lets the air through. Whatever you do don't take that gasket out, because it is oversized somehow and won't go back in. I ended up having to disconnect the water flow to that because I couldn't get it seal in a way I was confident in after removing that gasket
