If you've got a loud knocking noise and rough running with the CMP (Cam Position) Sensor disconnected then putting in a new sensor won't help that. Possible Crankshaft or Connecting rod bearing(s) for the knock.
If the engine is in good shape and the CMP sensor fails...unplugging it will allow the engine to start and run up to around 2500 rpm but still run smoothly.
Sounds like you might have bigger problems than a Cam Position Sensor!
What engine is in it? Also what does the oil level look like and the color of the oil?
