Not on any car I've ever driven, it isn't! :-) I've never had one idle at even 1000, 500-800 has been the norm. I did have one that started idling at 1200, but that was because a vacuum pipe had become detached, and it was the ECS's way of saying that something was wrong - it didn't have a "Check Engine" light or anything so it set the idle revs high as a warning that it wasn't happy.
