SEE THIS PAGE YET,?
THIS SHOWS THE IAC PLUNGER DEVICE, IF DEAD COLD START EXTRA AIR WILL BE DEAD. AND WONT TO STALL ENGINE.
first test the plunger. It works exactly like the coolant thermostat with a wax core, that expands hot and cold fast idle ends as plunger retacts.

the Maf can be cleaned gently with mAF cleaner, or other plastic safe cleaners, with the nozzle stay at least 8" inches away, spray count to 30 , repeat say 3 times.
it is very delicate sensor do not blast it like mad or for sure dead close or $$$ costs.

the plunger holds the TV open, cold, it must.
then when not the plunger retracts leaving a GAP from it to the TB throttle bell crank (and cable)
i forgot i made that page 10 years ago.... for a friend with 1.8.

the thermostat must go to 180f and old and is the first test on all EFI cars made, but that takes scan tool to do that right.
the scan tools proves that works and the ECT sensor that read water temp, are both proven to work at the same time.
The EFI PCM runs differently cold engine and hot, totally.

any scan tool 2008 or newer will have all 4 sets of pins, and scan for sure any car made in USA 1996 to now.
