July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Component Testing

  1. Ignition OFF, disconnect the harness connector at the ISC motor.
  2. Test the resistance between the idle switch position terminal 6 and low reference terminal 8.
    • If the resistance does not change as the throttle is opened and closed, replace the throttle body.
