Running like crap when it's cold outside

So winter hit Norway just recently, and I was hoping to get to use the Dart from time to time even tho its winter, because its my only car.
But I have driven it a couple of times in about 0-5 celcius and it just start and run like crap. Getting it to start is hard, and getting it to run at idle takes time, and even when the engine is hot it still runs terrible at idle.

Is this just the way an old V8 acts in cold weather or can I do something here?
