Troubleshooting Hints
Hint 1: The Idle Air Control
(IAC) valve position sensor is the most important sensor for controlling the idle speed. If a malfunction develops when the engine is idling and the engine load is varied by turning the
air conditioning switch to ON and OFF, etc., this sensor is probably defective.
