CB1100 Idle speed instability problem

[dave]

Because i did some tests on how the iacv works and the help of popgun we know that the iacv is a busy part, it does a lot of work around the normal idle position, because the way the software inside the ecm is written every time the throttle moves the iacv is told by the ecm to move a few steps in the same place, in anticipation of the real reason why this is the case my thinking is that some of them do not stand up to this amount of work in this spot and have difficulty moving small amounts, they are quite delicate parts operating in a hot place, but when the engine is restarted the iacv does some more traveling and is able to overcome the sticking point and temporarily behave as normal, again, just my unconfirmed speculation.

This is a great explanation Max, thank you! This cleared up a lot of questions I have been asking myself.
