So I've come to the conclusion that the all-impressive 949 is busted. I wonder if it has something to do with being a 6V servo instead of a 4.8V one
Do I need a receiver pack on the car too? For right now though I just went out and bought a HiTec HS-225MG. Do you guys think the KO is busted?

Before you start tearing into that servo, check your servo saver. Servo savers on 1/12th cars take a lot of abuse and they can develop small, almost unnoticeable cracks down the center of the horn which will manifest itself as the servo not centering.
Also, you did not mention if you have the servo bolted into the car or servo taped/shoegoo'd to the chassis. If it's the latter, then the servo tape/shoegoo can get old and allow the servo to move under load taking a new set after each corner.
