yeah Duh!! engines arent supposed to be driven on unti theyre warmed up, the oil spread around the parts, etc. let it idle while you drink your cocoa and warm it up then drive it and it wont run so rough. your engine will thank you.It requires less time to get to normal operating temp when the outside air is warmer because it doesnt have to warm up as much..again I say DUH!

Your truck should run smoothly at 23 degrees. You dealer should fix this under warranty.
