Temps where I live are not harsh, 40 degree nights over the past few weeks, and it does it after having been in the garage as well.
Thanks for your comments

mine does same exact thing. dealer couldnt reproduce it. not an issue to them, but odd to me. rpms will jump around from 800 to 1200 and back for that first 45 seconds or so.
