Good Moring,
Just thought I'd share my solution.
The auto-choke module, see above picture (thanks FixKick) was blocked with gunk and rust, as were the inlet and outlet water hoses. If you look at Fixkicks video on induction hose routing on his 95 Sidekick, you'll see all those hoses, first leading into the IAC then on into the auto-choke module that's screwed into the base of the throttle body, then back into the base of the thermostat housing.
All I had to do was clean out or replace all the hoses and auto-choke module, make sure the water flow does what it's supposed to and voila! Fast idle drops down to normal idle as intended after the water heats up a bit. Confirms the IAC is working as advertised.
I guess there's a couple of learning points, keep the coolant clean and inhibited at all times and don't use the gunk you can buy to stop radiator leaks because it'll probably block those small water hoses.
Good luck everyone!
