Idle issue on an 89 sidekick 8v

[Freaky Beanie]

Yes, it's an amazing tool to have handy in the garage
I will do the heat test again without the putty in the IAC.
I will do those tests this week when I get more time.

the FLIR shows all is good, heat wise. nice way to test this. FLIR.
if the IAC is roasting hot like the FLIR shows, the IAC is bad if it leaks air, so adjusting it is ok, (nothing to loose only gain)

and thanks very much for sharing FLIR here,

It is shame the IAC can not be removed like the 16valve has.

good luck to you!~
