Okay I have pulled all of the egr components off (pulled out butterflies and the rod that they attach to which left holes in the runners inside the intake manifold would this cause a whistle sound at idle and cruising speed) so I guess its not egr related. Cleaned the iacv I only have one code and its egr related so it shouldn't affect the way the car idles. When I crank the car up it shoots to 2000 rpms and comes back down to like 1100 rpms. It has a slight stumble at idle(you can feel it through the shifter) and also when your cruising on the highway.
Also when i just blip the throttle at idle the rpm's will shoot to 2000-2200 rpms and come back down and hover at 1500 rpms. Sometimes it slowly climbs anywhere from 1400 rpms to 2200 rpms.
Could anybody point me in the right directions thanks.

Re: High Idle KA24DE (hinds90)
uhm.... the butterfly flaps are there for a reason guy.... to help the car IDLE correctly! put them back on and i bet you your engine will idle just fine. i have EGR removed off mine but i still have butterfly and it has good idle right at 1100-1200. with EGR off its going to idle high so just know thats not gonna go away unles you wanna do some tweeking. i just left mine alone. open header and high idle sound evil.
Re: High Idle KA24DE (hinds90)
Did you try restting the idle after doing all this? That could be why it idles high. http://www.nicoclub.com/articles.php?id=161702 That's to set the idle. You should also make sure there are no vacuum leaks caused by removing the butterfly valves.

Re: (jtolton)
You can run without the butterfly flaps, you just need to fill the holes left by the rod that supports the flaps. This is your problem.
