First, if you haven't had a tune up for some time, you may want to consider that. Worn plugs or a weak spark can cause problems in the cold when the fuel mixture is richer. It can't burn all the gas. Also, there is a temp sensor that tells the computer how cold it is outside and the coolant temp. Based on that information, the computer determines how rich or lean to make the fuel that enters the engine. If the sensor tells the computer it's -50 degrees F, the mixture will be too rich. Have that checked too.
