On my 07 GT,When the car is cold The rpms go to 2000 and slowly come down, I would say 1500 in10 seconds and 1000 in 45seconds. Does this happen to all?

I just cold started mine. I did 2000 RPM for about 1 second, then dropped immediately to 1500 RPM and in about 10 sec dropped again to 1,000 RPM.

The colder it is outside the longer it will rev higher before dropping down to the correct idle. When it was below zero the past couple weeks around here it would rev at around 1500rpm for like 3-5 mins before dropping below 1000.
