As I read my Digifant ProTraining manual, the idle stabilizer is to be
checked with oile temp at at least 176 deg F., which means it is NOT
isolated with a warm engine.  it is still working to move the timing back
and forth a few degrees to hold idle stable.

Subject: Re: Bad Idle Stabilizer?

AS I understand it, with the engine warm, the idle stabilizer should be
isolated from the circuit, and not  have ny impact on how the engine
idles. But if it is faulty, it very well could, if it is hooked back
into the circuit. I currently run with mine disconnected because of that
very reason. Disconnected it works great, but connected it makes the
engine jerk and buck.

There are three areas where the idle stabilizer system becomes active.

Cold start
Turning the power steering to the stops will kick it on to idle the
engine up so the pump load won't stall the engine,
When the AC is turned on, it will kick the idle speed up to carry the
added load without stalling when stopping at a light or otherwise being
slow.

Outside of these, if the system is working correctly, there should be no
othere impact. The ISV is out of the circuit.
