Can any body will help me to rectify engine speed reduction problem when the ac is switched on? The idle speed is 1000 rpm but it reduces to 650 rpm when the ac is switched on..the diagnostic scanner does not say anything about it .

idle speed learning procedure
With a cold engine: Turn off all accessories.Disconnect battery for a few minutes. Leave the hoodopen.
Reconnect the battery. Do not turn on any accessories.
Do not touch the throttle. Start the engine at 3000 rpm until radiator cooling fan turn on.
let engine at idle for at least 15 minutes.That is it! Turn off ignition switch, close the hood.Now you will need to reset radio stations and possibly the drivers "AUTO" window feature. If the "Auto" feature stopped working, activate the auto feature and while holding it in auto, run the window to the bottom. Then activate and hold the switch and run the window to the top and continue holding the switch an additional 3 seconds. Now the auto feature should work.
Thanks to all for suggestions.
