high idle

5

Asked by Feb 14, 2011 at 08:53 PM about the 2004 Ford Escape

Question type: Maintenance & Repair

In park it runs at a very high rpm, I have two codes being detected one is the idle air control valve (IAC) rpm higher than expected and the other is the (IAC) valve circuit malfunction. I replaced the (IAC) valve, and ran a vacuum test, which read perfect. Any ideas?

take the IAC out and clean with carb cleaner,they will get carbon build up in them,DONT push or pull the plunger looking thing when it is out spray it good then spray a little W D 40 in it reinstall ,you will have to unhook battery to clear computer,do this first install IAC plug the plugin back into it reconnect battery crank,let it idle a few minutes for computer to relearn IAC.

The (iac) is brand new

possable bad TPS,or you have a vac leak,no matter what test said,you could have one so small it would not pick it up.

Had the same problem, unplugged the battery, cleaned out the IAC valve with carb cleaner and moved the plunger back and forth (before I read this) and hooked back up, runs great! TOO EASY! Took me ten minutes and i didnt check anything else, swear

My 2001 Escape had a 4 to 5,000 rpm idle when warm and put in park. I found this article very helpful. Replaced the IAC, no change. Disconnected and reconnected the battery and no longer has the high idle in park, when warm. Thanks!

an easy way to test the IAC , unbolt it,put it aside, do not unplug it, with a piece of metal or wood , simply block the holes and leave a tiny passage for the air, have someone to start the engine for you and if you can control the idle RPM like you want by letting the air in, it mean you dont have any vaccum leak and the IAC is the culprit, when installing a new IAC, you must unplug the battery to reset ECM ! good luck !

Engine Rams when after 1800 will not idle back down unless put in nuetrual then back in drive. With air con on will continue running higher rpms. Put in nuetrual won't help.
