I know this is going to be a gravy question for any Z lover, but I am having trouple tracking it down. Some guidance would be greatly appreciated!

I have a 1991 300zx N/A 5sp, and I cannot for the life of me locate the idle adjustment screw. I know it is attached to the IAA and the air regulator, but.....

An idiots guide to locating it inside of the engine bay would save me a trip to the dealership and help a fellow Z fan out in the process.

Thanks in advance.

Check Riz's Link page for the FSM or a tech article next time. You can find the link in his signature or as a sticky in the Z32 forum.
Here is a link, look at picture 2. The idle adjustment screw is on the IAA, make sure to disconnect the connection to the air control first. Its all on the page below.

if you have a high, or unstable idle, DO NOT just go and adjust your idle screw.

do a search if youre having idle problems

Hay,
I appreciate the responses, but I am having a time physically locating the IAA inside of the engine bay. I know what I am looking for, as I have already looked at the link posted.

The idle is low-->around 600rpm, which I believe is causing it to stall, when I brake to a stop. I am trying to figure out what is the underlying problem of my stalling/idling issues. I have already checked a ton of links dedicated to this issue, and I am working on this idle issue right now.

There is about a million and one things that could be causing it; it seems like anyway. I would like to solve it myself before I get taken to the cleaners at a Dealership.

then i would still not reccomed you adjust the idle screw just yet. disconnect the AAC and see where the idle goes to...and check the list at where it should be

the IACV is on the drivers side at the very back corner of the engine. id suggest taking that and the air regulator off and clean and ohm test them. good luck

Thanks for the feedback, its greatly appreciated. Its on the books for Sunday, I will give a break down of how it goes. Wish me luck!

you should NEVER have to touch the idle screw on a z32. all you will be doing is masking the real problem.

i think i already said that twice
