I have a 91 Accord EX, where would the idle adjustment be on the throttle body. My idle is to damn high, 1500 RPM.

your thought would be oblidged!

Be sure you have slack in the throttle cable.
Check for vacum leaks.
Unplug the IACV and see that the idle drops about 200 rpm.

 

lol good call, 1991 Accord EX. My friends are telling me it's some kind of screw on the throttle body. But i'll check you other suggestions to.

is the IACV located behind the intake manifold next to the throttle body or is it under the throttle body ????

 

Seems like most hondas have the idle screw right on the throttle body, it might be covered with RTV or silicone to keep it from rotating...

Procedure should be:
Fully warm engine up
Unplug IACV
adjust throttle screw with flat blade screwdriver to BASE idle rpm (prob 600rpm)
plug in IACV and idle should jump up to about 750 rpm
turn off car
clear ecm memory
done

This is for a 5th gen, so your car may require slightly different steps and RPM's

sohc

 

FYI If all of a sudden out of nowhere your car starts to have a high idle that would indicate that something has changed. And that something would not be the idle adjustment screw. It doesn't move on it's own. It could be a vacuum leak, your IACV, FITV, IAT sensor, ECT sensor etc etc.... Check for vacuum leaks and problems in the idle air system (IACV-FITV) before you go adjusting your idle speed screw.

There is a lot of info on this topic if you do a search or read the FAQ's at the top of the page. For some reason there is a new thread on this topic on a daily basis.

 

Yeah What GhostAccord said X2

 

If you have problems on a car where a computer controls idle, don't just go and try to adjust it, find the cause of it.

x3 what GhostAccord said.

 

thankyou everyone!

much obliged!

on the 94-97 (vtec model anyway) i would imagine its the same on the others....the IACV valve is actually on the throttle body...on the bottom

All 94-97 Accords are as follows;

IACV = Behind the intake manifold
FITV = under the throttle body
