Toyhooter, I hope you found this place ok. That other forum has some traffic but nowhere near the traffic and resultant knowledge on this mitsu 4x4 forum. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Conclusion from all the feed back and actuall part replacement.
#1 throttle body failure is a known problem but rare
#2 hard to say if the failure you encounter can be fixed
#3 does not seem to be age or milage related. Fidle valve
fails because it wants to.
#4 replaced my throttle body and all is well again
and now the mitsubishi super happy bonus conclusion is
#5 my combination driving MPG has increased by 9.25%.
increasing from barely 16.8 MPG to 18.1 MPG
Thanks to all for great feedback information

Glad you got it fixed.
Can I have your old throttle body?
I just want to tell you both good luck, and we're all counting on you.

Good fix. Glad you figured it out. Wonder how many bad fidles there are out there now...

Sorry. I left the old TB with the dealer. I usually ask to keep old/defective parts. Not this time. I guess I draw the line between stuff I might be able to rebuild and stuff that will just hang around on my work bench.

I know this is a old thread but I am trying to figure out a high idle problem (2k hot or cold) on an 89 3.0 montero. I am at the point of replacing the TB. I was wondering what a Fidle valve is and if the 89 has the same thing. I have covered the entire TB and intake with soapy water hoping to get some indication of a vacuum leak but nothing.

Replace the TB - Recommend Wrecking Yard Part First

The thread is old but it varifies what I experienced earlier this year. I had a fast idle and I did all the things mentioned in the FSM and by folks here on the forum. I was scared away from buying a new TB by the price, so I took a chance and went to car-parts.com and found a wrecking yard in ID that had a TB for my 89 3.0. I got it for $65 including shipping to WA. My idle is now adjustable and stable right on spec. Since the guys here say it is a rare failure, your chances of getting your idle fixed with a used TB may be pretty good.

I did that with one of mine. Couldn't get the idle to come down. Finally traced it to a bad TPS sensor. I got a TB from a yard, slapped it on and no mo problem. I got the one cause I played with the idle screw so I had no clue where it was stock.

Hey thanks for the reply! I have filled out their parts finder deal and I am waiting for a reply. They did not have one at the time I looked today. I contacted the salvage yards around here and no one has one.
I would love to find one and try it. I have my doubts that I could even find a new one for any price.

I got the one cause I played with the idle screw so I had no clue where it was stock. Thanks for the help. I have replaced the TPS and the ICS, cleaned the TB really well. I have had the ECU check out and it was fine. I must have a vacuum leak but I can't find it. My assumption is that it is leaking somewhere in the TB. I commented over on another thread: http://www.4x4wire.com/forums/showflat.p...;gonew=1#UNREAD about this. There is some sort of wax pellet that controls air in the TB during cold operation. I don't know if this is part of my problem cause mine stays at 2k hot or cold.
