Thanks for the feedback on this one Tom!
Now it must be the wiring, because my independent already replaced the Idle Speed Actuator 2 months ago, which incidentally lasted about half the day before the ASR light came back on. The car is fine, I have just learned to ignore the light but that is getting old real quick.
So now I'm wondering if bad/old wiring can produce this symptom? Looks like its time to turn some wrenches.
