There are a number of things that may cause the car to hesitate when accelerating when cold such as low fuel pressure, a dirty or faulty mass air flow sensor, clogged or dirty fuel injectors, or potentially a bad oxygen sensor that is not heating properly. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
