if it only does it when the engine is below 50 degrees, i would think that there is a problem with the coolant temperature sensor for the computer. but does it set the light immediately when ambient temp is under 50 and coolant temp is inder 50, or will it set the light if the engnie temperature is warm and the ambient temp is under 50? if it is the later there may be an issue wiht the ambient / intake air temperature sensor. then agian weak fuel pressure can cause issues with colder temperatures since it requires more fuel to run an engine in the cold.
