Doesn't the Stabilizer control come into play when the AC is on, as in
providing a signal to the ECU to kick up the idle speed to 1500 of so
when the AC is on.and the throttle is set for idle  as in at a stoplight
or something.?
Without it there is difficulty in keeping the engine idling when the AC
is on. Engine will stall under the load of the AC.
