right my cossie idles fine when its warm and you disconnect the idle speed control valve connector plug. but as soon as u plug it back on the idle jumps up high ans starts going up an down an hunting kinda thing.

and when u pull it off again it sounds fine. and idles on the first line up on the rev counter think it stands for 750rpm.

anyone know whats up with it?

i'm trying to get a nice clear idle sound which is constant from my car. I only get it with idle control valve disconnected though, but i know i need to use my idle control valve for winter cold starting up etc, so need to get it working properly

cheers
