Try Air flow meter sensor cleaning by yourself couple of times when car is cold and see if it helps. Or else change the AFM sensor.
For cleaning it buy 10 aed carburetor cleaner, open air filter box, and inside the top cover there is mesh protecting the AFM sensor. Start the car and spray the carb cleaner on mesh and car will stall in 5 seconds. Wait for 1 min and start the car and do this again 2 times.
Try his cleaning for 2-3 times in a week, it should make a noticeable difference in hesitation. If it doesn't you need to change the AFM sensor which is bomb expensive mate.
