ICV goes to full closed position after turning key to ignition :/

i think i have the same problem, when you remove the valve and shake it, do you hear it move back and forth?

on a cold engine my idle is stable and high as yours at 1000rpm, when the engine is hot it goes down to 700rpm. the thing is in order to achieve this the accelerator cable is quite tense and i dont think the accelerator is fully closed. causing the engine to never go into fuel cutout when coasting. if i losen the accelerator cable, the car still idles but at 400rpm. the tach is still stable, but you can hear the engine strugling to keep idle (specially if the trans is in R or D the car will rock back and forth).

if i remove the valve cable, the engine wont idle, so the valve is doing something, but it may not be working at 100%.

have you tried to clean your valve with carb cleaner or WD40? i did that with mine when i initially bought the car, idle was a mess back then, and improved quite a bit. it was REALLY dirty inside.

Interesting. In the Bentley's Manual there is a description on how to set the accelerator cable, by the way. I also heard that the throttle plate itself can get clogged and not fully close.

I cleaned the ICV with carburetor cleaner. Before I put it back in I want to measure the injectors resistance and the valve lash however, so I can tell you for sure tomorrow
