Alright, so I was told that I could clean the Idler Control Valve, and I did.... only thing was, was that there was only 1 screen that was in it, not two. So, my next problem is...

The car Idles fine now, in the morning and all, except for after I keep a steady speed on it (like the interstate), then when I go to stop my car is idleing at 2-3 grand. Is this still an IACV problem or is it something else??
