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.

There is a Tecnical Service Bulletin (TSB) that specifically addresses codes P0120, P0220, and P1516.
It says that the TAC Module can set these codes erroneously under certain conditions. It is very likely that if your vehicle is diagnosed according to the provisions of this bulletin, the problem can be corrected without having to purchase or replace any parts.
It is Technical Service Bulletin number 03-06-04-032
