what do you mean between 0 and 2? like 0rpms and 2,000rpms?
did it only do it on start up or does it do it altogether at idle? any accelerating issues? and does it subside once the car warms up?
It can be several things from, bad spark plugs/coils/vacuum leaks/faulty fuel pump/dirty throttle sensors/injectors which are some of the more common ones to several other things.
So a little more info about the symptoms could be useful along with more info about the vehicle such as mileage, recent maintenance etc
Also a quick
would guide you on the right direction and show you the symptoms of the more common reasons why the car would sputter
