I recently bought a PLX Kiwi and was looking at the sensor diagnostic info that was being displayed. I played with it a little bit to see if the it did anything. Using the A/C puts more strain on the engine (doing approx. 10-15% more work), so while it may not directly affect the MPG, it is causing your engine to work less effectively and thus causing worse gas mileage.
