I was just reading a post in the Seville forum about not letting the car idle and warm up for 10 mins but rather wait a few seconds for the rpm to come down to 900 and then drive. My car starts at 900-1000 and stays there until its warm and then it comes down to 600. This only happens when its 33* or lower. Also the A.I.R pump doesn't run when its that cold either. I couldn't remember the car doing this last year so I started to check things out but it doesn't seem like there is a problem so I let it go until I saw that post about the Seville.
