hi there. the reason that the engine idles good when the air-con is engaged is that ussually all vehicles nowadays have a vacumm advance mechanism. this is triggered mainly by a electric solenoid valve which is also attached parallel to the source supplying power to compressor. a small vacumm hose with a diameter like a common pencil or ballpen case. its made of rubber and it runs from the alternator vacumm pump then to the solenoid valve and to the vacumm advancer unit attached to the injection pump throttle. this system raises the idle a tad higher.
if your montero runs completely normal and you experience no other problems with your engine except for your present problem, then the solution is just raising the idle a little higher. if your montero is equiped with a RPM guage on the dash, try adjusting the idle to around 800 rpms. it would be healthier for your car if the idle raises a bit when you engage the air-con because this would compensate for the added load on your engine.
hope this helps.

the purge valve is part of the EVAP system. p0441 is usually set when the ECM can not monitor the purge valve performance. the EVAP system takes the gas fumes out of the tank and purges them into your intake system while you drive the car. if the ECM doesn't see a drop in fuel tank pressure then it sets the code. most common failure is the purge valve malfunctions or loss of power or ground signal to the purge valve.
