it seems to vary if the ac is switched on/off.......atleast by 500rpm....
could it cause any harm...

when the engine is cold it's perfectly normal! the ECU for the 1st 90 seconds keep the engine rpms at about 1500, then, when engine is warm gradually go around 700800 RPMs >>

I always wondered that. It used to scare me when i got in my car in the morning and it revved itself up. GOOD TO KNOW!
