How do you tell if the Carb Idle Stop Solenoid is functioning or needs replacing? If it needs to be replaced, are they different between an L48 and an L82 of the same year? Is this a true statement? "The idle stop solenoid is not energized unless an air conditioning function is selected (MAX, NORM, BI-LEVEL, or DEF). When energized, the solenoid plunger extends, increasing idle speed to compensate for A/C compressor loads. A better name for this solenoid might be "air conditioning solenoid" since the solenoid only controls idle speed during air conditioning operation".
