There have been a few topics like this.
Some peoples cars idle comfortably as low as c700rpm, others idle quite high, around 1500rpm.
The general concensous seems to be that as long as you idle is somewhere in between these points, and isn't overly lumpy, that this is just the 'personality' of your R coming through :roll: :lol:
In other words, they all seem to be quite different.
