On my car now controller outputs around 1000 mA but idle on neutral is still around 900 rpm. Guide defines current 700-1000 mA when engine is idling warm. 12 v shortly to ICV will stall the engine. Possibly there are vacuum leaks as the car is old but economy gauge goes all the way to left on idle. Anyhow some previous owner had partially plugged idle air passage at front of ICV to make the car idle somehow. It is possible that he has adjusted air flap stop too to get idle adjusted.Throttle bar is not under tension when idling. Idle switch gets activated when pedal is not pushed. I'll take a look how and where the air flap stop is adjusted.
