To reset the idle u need to reset adaptive values, if u swap ecm , change iac valve , or the ecm has a hiccup u must reset it, ive not had to do this but 2 times? 1 was when my ecm got wet bad
I had at first taken it to the dealer they had a guy work on it that did not know gems, he drilled the intake told me cant be fixed when i specified to reset ecmi ended up buying another used intake and having an independent shop reset it, DO NOT DRILL THAT INTAKE PLUG
guy im friends with at dealer now has no idea why someone would have done that
I had to have an Indy mechanic reset the adaptive values witj TestBook on my 98 twice. My 96 hasn't needed anything. And my 94 doesn't even have that option.

Ooooohhh, you need to reset it after changing the IAC valve. Had no idea.
I’ve been chasing high-idle issues on cold start...like 2k rpm, then it would settle down to 1100 when I took it out of park. Warm starts were better afterward.
I changes my IACV a while back, didn’t seem to be associated with it.
Just changed my MAF to one of my backups...now I’m the opposite with warm idle at 400rpm.
Just a quick update on what I thought was my high idle issue. All this time I was looking at the tach gauge and it looked high, it also sounded high. So today I changed my UltraGauge to read RPMs and would you know it, it was reading an idle at 900rpm at all!
From the image provided does this look like I am in the safe zone?
I cleaned my throttle body, and have a new IACV coming. With this reading should I clean the installed IACV? When at idle the tach doesn't bounce all around it stays steady as in the picture. By the way according to the image what RPM is being displayed on my gauge? Is my Rover gauge off and I shouldn't trust it like I have learned not to entirely trust the temperature gauge?
