simptoms were surging idle after warm- up. Following the fix the idle settled down nicely.
best repair I have done in a while - no new parts - just a little twisting action from a screw driver!
yea this is always the first thing i look into when anyone with a civic has idling issues.
on my previous civics i would actually just take this part off complete and plug all the holes and lines. the iacv did a great job maintaining a cold idle.
i avoid going to the idle screw at all costs.

You guys screw the valve all the way completely down?
As far as I know, from the factory, they are adjusted a few turns out. I tried to adjust mine all the way down with no success. The only way I could get the car to run proper was with it adjusted a few turns out.
