Land Rover Repair: 2000 discovery

Answer
Misfire codes are from ignition issues, or internal engine issues.  The crank sensor is not going to cause those faults.

As for the three amigos - you will need to scan the SLABS computer and see what faults you have.  Could be sensors, controller, other possibilities
