93 Acura Legend 3.2L V6 idling from 700 to 2500 Sign In

1993 Acura Legend with a 3.2 L V6 with 158,000 miles is idling wildly.

With the car sitting in Park or Neutral with A/C on or off, parking brake set or off the RPMs go from about 700 to 2500 up and down and up and down.

Ideas/suggestions, Please!

You may have a bad IAC ( idle air control) but try eliminating any vacuum leaks and cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

Thanks. We are going to do all the cleaning you suggested AND we are probably going to replace the IAC.

One other thing...I disconnected the IAC and started the car. No change. Then when I re-connected it, the idle surging was much more rapid. It actually idles at 1100 when the car is first started cold. Then goes from 1100 to about 2000.

I'll come back after we finish with the recommended cleaning and other repair to let you know what we did that worked.
