Hello..My 91 3.0 just started all of a sudden idling high..! It idles in park around 2000 rpms. I took off the IAC cleaned it,replaced and it actually idle down to normal. I then shut off the engine came back about 30 minutes later and it started idling high again! Thanks..!
BTW, with the truck running, I can unplug the IAC and it still continue to run at high idle.So this means vaccumn leak some where else? There is a leak coming from the brake booster hose grommet especially after you shut the engine down you can hear it and when you push around on the fitting going into the booster, it stops leaking! Could this be a contibuting even though the leak was there before I started getting the high idle and it ran normally..Thanks..!
