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.

Poor starting when cold indicates choke problems, make sure it is closing when cold and opening as it warms up, to test cover the throttle body with your hand and have someone crank the engine when it normally would have trouble starting and if it starts right up but dies when you remove your hand then that is it, also check fuel delivery such as fuel filter, and spark plug condition.
