ok, calibration was done once in the factory
they would use hot water to do that,
in your case a pan of 150F water, heated to reach this critical temp.
the turn said ring, to the KISSING point of the coin to ring, just blocking off air flow.
then (used condtion, in this case) test it in ICE water next to see if it opens the correct amount just as my photo shows, I did -10F and 40F and 150F. I tested it at 3 points, to see it if is working and is it linear.
or dead.
if you set the 150F point, and find out it does not open at -10F full that means its dead if is dead, or way the hell off due to aging of the WAX pellet inside, as ALL DO old.
all thermostat (most) die at 7 year mark for this SAME aging effect.
no wax pellet lasts forever, not one.. sorry
this IAC is bad or water does not flow throught by any means., on cars coolant paths can packup in junk ,rust or grime or bad coolant or wrong gaskets.(or packed up inside the IAC itself)
that is why I wanted to test the IAC first and not wreck the factory calibration. I test all that first. if the ICA is just off a bit , re calibrate can work.
Its ok, the thing is old best is having a spare TB , and ECU, 2 parts to have spares just for days like this.
