Me either... my Jeeps stays parked in a garage overnight and when I start it it stays at about 1K RPM for maybe a couple seconds then settles down to about 700-800.

Re: Long idle down time

According to a Jeep engineer's response on Jeep Garage:

The long idle down time is so the oil can circulate through the engine.. one should wait for the RPMs to drop on a cold day but on warmer days it's fine.
