Possible IAC valve problem...need help.

[SE1904]

So pretty much, I have somewhat of a rough idle and when I shift gears my RPMs bounce from high to low or low to high. I am thinking it may possibly just be an IAC problem...the problem is...I am having a hard time locating it under the hood. Any help is welcome. Thank you.

I have a 1995 Toyota 4Runner SR5 V6 3.0L 3VZE engine.

From what I have been able to research they are integrated into the air flow meter. I could be wrong on this

I'm not sure on the 3VZE but typically the IACV can be found on or near the bottom of the throttle body there will be 2 small coolant lines running to it so should be a dead give away. A sure fire way to diagnose a IACV problem is to tape off the little hole in the TB just in front of the butterfly, if the problem goes away once taped you have a IACV problem which can usually be fixed with some compressed air.

Its built into the throttle body heres mine with the little cover plate removed.
