1991 Nissan 240SX Question: How do I fix a high idle problem?



, Victorville, CA, September 24, 2012, 17:22

The car idled at 1100 rpms. I tried to adjust it with the idle screw, and it only dropped down to 900-800, and then the idle started fluctuating around that range as well. How can I fix this problem? I can't lower it any more with the idle adjustment screw.

    sounds like you may have a bad idle air control valve, i would replace it and see what happens, also check for intake leaks

    And will probably want to return adjustment screw back to original position.
