White smoke and rough idle only when it's cold weather

{"text":"I have a freightliner cascadia dd15 engine, and so when the weather is cold outside it starts to emit white smoke and refuses to accelerate, but after awhile it stops when I increase the speed. But if I lower my velocity to about 25 mph, it starts to emit white smoke again. Why is this? If this has happened to anyone else, what did you do to fix the issue? ","pics":"[]","canComment":true}
