Issue with motor spinning

Hi,

I am flying an X8+ from 3drobotics and have noticed that one of my motors spins very slowly and jittery when armed (see video: https://drive.google.com/file/d/0B29Xl-oYL0vjcmtTRkQ4UzIxNFk/view?usp=sharing), but will spin faster when the throttle is raised and still flies fairly well in Auto mode. However in Loiter and Alt Hold, the issue is more pronounced where the copter cannot keep a steady heading and will yaw slowly due to the slower motor.

I have replaced the motor and still have the same problem, although the wiring still seems fine too (there is a small cut in the covering of one cable from the ESC but the wires themselves aren't affected - see picture attached). Could it be the ESC that is damaged and how should I go about troubleshooting it? If anyone has had the same problem or has any ideas I would greatly appreciate it.

Thanks,

Lucy
