I repeat: this is not normal behavior for the car.
Your motor has a system that is designed to raise the idle in cold weather by a total of about 300 rpm. If your idle goes all the way up to 2000 rpm when cold, then you most likely have a bad fast idle thermo valve. You should check the valve using the procedure I posted above.
