wife at work.? Grin
super easy, in pan of hot water.
even frying pan of hot water, with thermometer clamped to the pan, and at 150f it is 100%. closed.
are you sure you cars thermostat is good, or some goofy guy put in a silly 160F stat? (or none at all, OMG) I know it's new but currently, I am unsure on the temp rating and will take a look.
you could buy a 195 (or 193)F stat and run that and see if the IAC closes. (band aid fix)
or use the frying pan to learn exactly what temperature yours closes 100% super easy.
the cars gauges in the cluster are just toys, never use them to diagnose engines, use real measurement tools. gauges.
I use an IR gun, for $15 that works great. the truck is not ready for road yet. I just let it idle in my garage (with an exhaust fan of course) I have a FLIR IR Camera so I will test soon. (Busy weekend doing plumbing for my parents so I may only have time next week )

to RAD tank after 20+ miles 100% fully hot engine.
then idled for 15mins.

running the wrong TB base gasket does that,

My IAC comes very hot but I will measure temperature with my Flir


the gasket there is very complex.
ever seen this.? no I have not yet

my TB slide show covers all this.

here is the SMP makers kit, it is easy to get the wrong gaskets, A/T car are different as are 89/90 and 91 to 95
top right is correct.

and RULE 3, these hole must be blocked. 5 hole here must be gasket blocked or be hell to pay HAHA [/color]

These are all used and probably have the same issue as mine . If I cannot fix it, I want to have a modified replacement. (you can get universal IAC units). My wife will be driving this sidekick and I want/need it to be simple for her.

150F it closes. fully
that assumes you thermostat in your car is 180F or higher, and actually works
yes,. me too, id not give up on it, 30 years is young if you do the work.... nobody does that, just us, and good luck to you !!!!

first prove what is wrong, then hack it.
these TB are rare so needs extra care to now what is wrong.
the thermostat needs to be at 180first
the water flow true the IAC body must not be restricted in any way.
if all that is ok, the IAC is bad, hack away.

I'd have in in hot water, 150f and see if it closes, if it is only a bit off, turn the ring inward so it just hits the piston and no further, the test at 150f again, and repeat until it is right.
that is how to calibrate it, if you want to know..
guessing will mess up the calibration and the ECU will not like that, it knows the actions of the IAC and injects fuel based on a model of those actions. (cold)
cold to 150f and then its offline. the IAC.
hope that helps..... good luck
