Hi there. Check the idle air control valve (IAC) and see if its working. The IAC is designed to make the engine run at idle in all climate conditions. Also, check the mass air flow sensor (MAF) and see if its dirty. If a MAF is not working properly, then the engine can stall out and even cause the engine to hesitate on acceleration at times. If you need further assistance with your engine stalling in cold weather, then seek out a professional, such as one from Your Mechanic, to help you.
