My 04 used to have a fairly rough idle, for about the first 60 seconds on a cold start.

It would be in the morning when it dropped to under 50° in the garage, and I did hear some front area, dash/windshield rattles.
The last software update, done when it was in for an oil change, cured it. This past winter, it starts/runs as smooth cold as at operating temperature.
The shifts for the first mile or so, still aren't as smooth as at operating temperature, but the rough idle is gone.
