Since you don't know what kind of car you have, the year or the engine size, I'l throw an idea-Coolant temperature sensor for the ecm. This reads the temperature of the engine and tells the computer parameters for the fuel air mixture. If the ecm gets bad info it may richen or lean out the fuel to the extent that it affects combustion.

When a engine is real cold, The oil in it becomes thick and heavy, The intire engine contracks and everything inside of it gets tighter then it would be if is was warm.
