possibly. but i've never another car do it. 2200 is so high, the car drives itself. not really very safe. and it never used to do it.What makes you think this is a problem? My '98 Grand Vitara (2.0 engine) idles at 1800 rpm on a cold start, drops to 1200 within a minute or two and idles at roughly 750 when at operating temperature - the actual rpms may change, but, most gasoline engines do something similar.
this bit of info would have helped if you had stated this at the beginning, so the excessive high idle is new.and it never used to do it.
