*** How-To*** Clean Your FITV aka Fast Idle Thermo Valve

Re: *** How-To*** Clean Your FITV aka Fast Idle Thermo Valve
My 92 tegra idles at about 1800-2000 constantly... its not just when its cold or until it warms up... as soon as I let off the gas it drops to where it should be (800-1000) then right up to about 2k. I am not very car savvy but I have been learning. So I am just curious if this would be the same problem in this post. most of the people with this posts issue describe a temporary idle issue that resolves itself after awhile.. mine never resolves.
Also, not sure if its related, my power steering is loud... I recently replaced the power steering pressure hose, the previous one was perforated with cracks... so maybe it's just loud because its under full pressure now.. not sure.
any insight would be appreciated!

Your fitv would be a good place to start checking....very similar to the problem I had...the rpm's over a period of time just got higher and higher...and I'm not sure about the power steering being "loud"? Do you mean a (whining) type of sound? If so, either the fluid is low or the pump maybe bad.

Re: *** How-To*** Clean Your FITV aka Fast Idle Thermo Valve
for cleaning the fitv, i know it recommended throttle body or brake cleaner, is there anything else that can be substituted for that?

Thanks for posting. I just fixed my issues with idling today. I found out that the plunger from the FITV came out from the threads. I just screwed it back in place also cleaned it too. Now problem solved! Thanks again!

Brake cleaner or carb cleaner works best and its dirt cheap and cuts right through the grime! its less than $2 at walmart and there everywhere open 24hrs. It also makes it easy cause you can use the straw and blast all the crud out.

Re: *** How-To*** Clean Your FITV aka Fast Idle Thermo Valve
I was researching the FITV and came across this thread. I saw lots of mention of no FITV on '96 and up Integras, but automatic tranny cars have the FITV all the way to 2001.

Re: *** How-To*** Clean Your FITV aka Fast Idle Thermo Valve
First things first, you have to determine if your FITV needs cleaning. Now if you’ve never done it before it probably does unless you bought a complete new one.
Reasons why you should take it apart and cleaning it:
-High idle before your car warms up, above 1500-1800rpm
-Lumpy idle
-Roaming idle
-Hunting idle
-Fluctuating idle
Tools Needed:
Ratchet
8mm Socket
10mm Socket
Pliers
Flathead Screwdriver
Throttle Body Cleaner or Brake Cleaner
Paper Towels
A cooled down engine for at least 2 hours
1) Now you got to locate where the FITV is. If your car is 1996 and newer you don’t have one. But for the older Gen 3 models like me, we do. Pop your hood and it’s located directly beneath the throttle body. It’s actually connected to it.
Attached to the FITV is one coolant line. This is how it looks with the intake on
This is how it looks with the intake removed
2) Now that we’ve located it, Remove your intake and strut tower bar (if applicable). Next remove the one coolant hose that is attached to it, using the pliers to loosen the clip. Have lots paper towels underneath to catch the coolant when it leaks out.
3) Next is to remove the three 10mm bolts located at the bottom of the FITV. **Note the intake manifold here is upside down to make it easier for you to see**
After it is removed from the engine it should look like this
Now spin it around to located the two 8mm bolts
4) After you located those two bolts remove them carefully and you should be left with this. Sorry for the blurry picture, I was cold and shivering.
5) Now unscrew it with a screwdriver
You should be left with this
6) Now take it apart and give it a good cleaning with the throttle body or brake cleaner. This is what we should have taken apart so far minus the cap and two 8mm bolts
Before
After
Semi put back together and cleaned
All cleaned up and back together
7) Clean up the inside of the FITV body like so
8) Now screw it all the way back in or back to where it was before if your car idles fine.
Side view shot through the hole. It isn’t screwed in all the way since my car idles fine at that position. Screw it in more if your car idles to high. The opposite if it idles to low.
9) Now put the cap back on and tighten the two 8mm bolts back down.
10) Reinstall the FITV back on your car following steps backwards from step 3 to step 1
Good Luck

I have seen mention of using grease, and silicone grease on the o-rings to make a nice seal.
Is di-electric grease suitable? My understanding is that it is pure silicone grease.

Just a tip if you guys see the "update your photobucket account for 3rd party hosting" right click the image and hit "Open in new tab" it'll open the image on photobuckets page.
I suggest anyone using photobucket to pull all your images down and start an Imgur account to host images.
