There is a cold start assist valve on the intake manifold. This is not giving the needed extra fuel to the engine during your cold start. It is conterolled by the on board computer of the vehicle. What activated it is a temprature sensor that tells the computer when the motor is cold enough to require the extra squirt of fuel. Most likely it is not functionong as it should.
Go to your local auto parts store and get a new temprature sensor. Tell the counterperson what your problem is and he will give you the proper part and if needed the location of it on the motor.
