Can someone help me with info abut the ICV? I've taken it off and cleaned it but when I look down the tube, the valve is open about 1/4 of the way. Have put 12v on it and doesn't move, doesn't seem to click or vibrate when it's fitted. I presume as it's a valve it should open and shut. How can I test it? Is the rest position closed, open or 1/4 way open?

My thinking is it has jammed and is stuck in a workable position. Does that make sense?

As I've changed everything else, no doubt I'll be changing the ICV too but would like to know one way or the other before I spend another weekend fannying about under the bonnet.

Symptoms, if you haven't guessed already, are intermittent rough idle/stalling at lights/surging/driving the wife mad

Have checked or changed fuel accumulator, injectors, plugs, dist cap and rotor,air sensor pot, vacuum hoses, OVP and Fuel Pump relays.

Some test info would help a lot.

cheers
