Can someone please show me a diagram or a pic of wher e the fast idle valve is.. ive been having bouncy idle now... not only when cold, but now when its wartm the car it still happens... thanks!

 

yeah i have the same problem with my lude and i to dont know where the fast idle thermo valve is located...

 

under the throttle body

you can take it off without taking the throttle body off, but its a lot easier with the TB off than on.

theres 3 bolts (10 or 12mm) and a hose or two connected to it, just take those off/out and replace with the new one or just take it apart and pull the spring inside it apart like 3/4-1 inch and put it all back together. then say goodbye to teh infamous-pain-in-the-***-wake-the-neighbors idle lol

 

aren't you talking about the IAC Valve?

 

does anyone know for sure that its the fitv because ive been changing alot of things like my map sensor and my idle air control valve and it still idle like crazy...

 

If you have an 92-96 Si/SR its that for sure...
i heard its a really common problem with the H23

 

if it hasnt fixed it yet... id put $50 on the FIV fixing your problem (btw i dont have $50 lol)

 

dude where is it? are you sure your not talking about the IAC valve???

 

kool yeah cause i have an 93 si and ive spent so much money on the wrong things

 

ya im pretty sure its that
now to find out where the Fast idle valve is located

 

under the throttle body

i just posted this somewheres else... look around this page or the 2nd page for another thread like this

 

and its easy to get to without removing it? what does it look like?

 

It's technically called the Fast Idle Thermal Valve because it's activated by heat with the wax it has inside...It's right on the bottom of yout throttle body-attached to it...Just block it off...

I did all this IAC and FITV stuff and none of it fixed my crazy idle, but replacing the intake manifold gaskets did fix it for good...they get soaked in oil from the PCV valve...

 

yup the post are right.its the fast idle control valve.happened to me before.what i did was checked all hoses for leaks and replaced the valve and reset the computer.bye bye crazy idle!
