Starts Subaru

1994 Subaru Legacy hard to start cold.?
I have new plugs, new son and new battery. I heard that could be a sensor temperature is more than one? How are they difficult to wear? A temperature sensor bad the engine light control over?
I do not think a temperature sensor would make your car hard to start are your temperature gauge. sensor map or oxygen sensor cause the check engine light We … but a car will work well with one of the sensors. Cold is the time we talk … maybe try a fuel filter and PCV valve
