idle goofiness problems

[imtjm]

Hi all,
At cold, my car idles at about 1000. When warm, it idles between 1500-2000. The idle control valve is turned all the way clockwise. There are no vacuum leaks as far as I can tell. Anyone know a solution? Is there a electric switch that tells the idle control valve that the engine is warmed up? Could this be the problem? Thanks for any help.

down and dirty fix

use a rubber faucet washer with a 1/4 inch hole to restrict the maximum idle speed.

Put this restrictor in front of the idle control valve.

Works for me.

The idle control valve opens and closes like it's suppose to do. i used a penny and drilled a 1/4 inch hole. it's maintaining an idle at 1100 with the idle control valve all the way clockwise. althought he idle is now at 1100, that still does not seem right. am i going to need to replace the idle control module? is there anything else? thanks.

I would replace the idle control if you want your idle to be normal, but if it was me I would leave it, its not using that much more gas.

replace the idle control valve or the idle control unit (module)? thanks
