The car will idle high until it reaches operating temperature. If you watch it, the RPM will slowly come down as the temp gauge goes up.

That's the car's warm up cycle.

Let it sit for 30-60 seconds and it'll drop.

My s2k takes about 3 minutes to drop from 2200 to its idle of 1000 if I just let it sit there.

My G used to take about 60 seconds to go from the warm up to idle.

I think this is normal. I notice that our cars usually reach operating within 30-40 sec.

Just noticed the same thing this morning, 3rd day of ownership and 70 miles on the car. Seems a bit wasteful in the gas dept. 70 deg isn't exactly a "cold start", does it take longer for the idle to drop in cold weather?
