What engine, as not on your profile

600rpm sounds about right for DBW v6, or a non DBW v6 with A/C on.  From memory, I think it should be 650rpm...  ...but my memory isn't as good as it once was

Just under 500rpm for a non DBW v6 with AC off also rings a bell.

As TB says my 3L[obviously non-DBW]idles at just short of 500rpm when at normal running temp with a/c off.
