check your tail pipe for a "clog" engine not breathing correctly.

perhaps you need a new cap and roter a new spark plug wire set. they don;t like moisture. also check to see if you have any broken or leaking vacuum hoses. the worse case senerio would be that your head gasket is leaking--at cold temps a little antifreeze will enter until everything warms up and it seals shut due to metal expanding. but since you say it's cold weather only--this probably wou;dn't be the case. good luck.

CHECK COOLANT LEVEL.CHECK THERMOSTAT.IF TOP RADIATOR HOSE DONT GET HOT IN 10 MINUTES AFTER FIRST STARTING CAR IN MORNING .AND JUST THE BOTTOM HOSE.THERMOSTAT STICKING CLOSE.IF THERMOSTAT FINE.PROBLEM COULD BE CLOGGED RADIATOR OR ENGINE BLOCK CLOGGED OR FAULTY WATER PUMP.
