My VR6 only warms up at 1k (or 10 because of German cars lol) and then drops down to maybe 5-6k for idle... Obviosuly it's not the same 2.0 like you, maybe it wamrs up higher rpms because it's a 4-cyl? My ol' 86 Corolla SR-5 warms up quite high in the rpms too, sometime close to 3k rpms.... But then again, it's carbuerated....
