Controller Issues

[domhehexd]

I've tried using DS4 to make my controller work on black ops 2 zombies, however there's weird issues with sprinting when I press the left joystick. Sometimes when I press it my character sprints for a full amount normally just how you'd expect, however sometimes he stops immediately after moving forward and I go back to walking, or I move a few a metre or two and it stops abruptly. It's really inconsistent. I can't really use it to sprint properly. I dont have these issues on any other games or on my ps4 so I was wondering does anyone know what's going on and a possible fix, please? Many thanks.
