Channel595 Posted November 21, 2010 Share Posted November 21, 2010 so i let some one borrow my car for about 3 months and now that it has expired tags and a high idle at about 1700 - 1900 i need to get it to pass. i saw this http://forums.nicoclub.com/iacv-aac-cleaning-and-testing-tutorial-t251133.html on another forum and i was wondering if you can take it off the pathfinder intake with out removing the intake manifold it looks like a tight fit. also there is an IACV and IACV-aac i cant tell which is which and in the FSM EF&EC -14 it shows the ecm controlled one with no connector on it and the temp controlled one with a connector? just as a shot in the dark i tried to use some intake cleaner and had no luck...

sewebster Posted November 22, 2010 Share Posted November 22, 2010 I'm not entirely sure what you are asking... I know that the AAC valve is basically fully underneath the upper intake plenum, and there is a connector that attaches to it, comes in from the back.

Channel595 Posted November 24, 2010 Author Share Posted November 24, 2010 can the aac valve be removed with out removing the upper intake manifold? Link to comment Share on other sites More sharing options...
sewebster Posted November 24, 2010 Share Posted November 24, 2010 I highly doubt it. There are probably a lot of things that can cause high idle other than the AAC valve though. Have you checked your timing, vacuum leaks etc? Link to comment Share on other sites More sharing options...
