High Rpm Idleing

I have a '88 Honda crx si with a Skunk2 Pro Series Intake. When I Start The Car it Idles at about 4000 rpm. I've adjusted the Idle screw and the little allen screw under the linkage. My ECU is reading that the coolant temp sensor is bad. I dont understand what that has to do with my problem but thats the only thing that the ECU is reading. Could this be the MAP sensor? or the Intake Temp. Sensor? Thanks for the help this, forum is great.

did you tighten it to the head good...sounds like a badass intake leak...or your throttle cable it too tight...?
