One possible fix could be a professional fuel system clean. Most shops offer this for $50-75. It does work, I've seen it myself and was previously hesitant to pay for 'snake oil'.
Ignition could be part of the problem too. Cold weather means condensation - does the car run well when it's fully up to temp? If it does, try spraying some water with a sprizer bottle on the plug wires and see if it re-creates the problem.
