Hi my dad has got a 1998 Ford Cougar 2.5 V6 and when the aircon is switched on the engine starts to hunt between 750 - 1100 RPM and continues to hunt while driving until about 2000 RPM giving a jerky feeling, this does disappear above 2000 RPM however.I would be very grateful if anyone could shed some light on this problem. Many thanks in advance for any feedback. Dean
