I have another tip for you ...
Your cold temperature sensor on the thermostat housing is probably shot ... not telling the cold start injector to supply fuel when the car is cold, so it runs too lean until it is warmed up.
Some advice - start the car and feel if the injector is pulsing ( the one with the blue connector on the intake manifold) if it's not, the cold temperature sensor as mentioned above, is shot, if you feel it pulsing then the calibration of the injector is wrong, or the injector is blocked, not spraying fuel anymore, but only dripping fuel, which is not sufficient for cold starts.
