So just yesterday my car started running horribly at idle after start, and the RPM just slowly puttered down and down till the engine stalled & died. It's been running for over a year just fine. After searching around the screens for what was going on, the IAC is sitting at its Hold Position (5%) and just sits there never budging even as the RPM drops. In fact, it never moves at all regardless of driving inputs. Is this a reading of its physical position (like it's stuck), or is this the requested position, and for some reason it's just not asking it to move. I changed its requested Hold Position and now it shows 10%, but I don't know if this means it physically opened more, or it's just asking to.
