Hi all,
I'm chasing an idle issue and it might be idle air control (IAC) valve related. Mine wasn't moving, but I disassembled it, cleaned it, and it moves now. What I learned while cleaning it is that the length of the moving part is adjustable.
I made a best guess at installation depth, but am not confident that I got it right.
If you have an IAC uninstalled, would you be wiling to share the depth that the plunger (looks like it may also be called a pintle) is installed?
The doohiickey in the very center of this photo:
I know I should just replace it, but the part is very expensive, even used.
My idle adjusts and is steady in stages while warming up, but when it gets to hot idle it fluctuates dramatically, very low and even stalls. The car catches itself sometimes and revs up. So I think my IAC plunger is moving, allowing more or less air in, but maybe the depth at the mostp closed position (stepped out) isn't right, so the correct amount of air isn't being allowed to bypass the throttle plate?
I know its a long shot, but maybe worth a try?
If I can adjust mine to the proper depth, thats one less variable.
