My 98 Cherokee limiteds engine light has been on about 3 times for the Camshaft position sensor but I got one from my cousin who works at advance auto and it still came up on a scan tool, so I took the sensor out underneath the distributor cap and I notice that the rod in their has some movement on it, and from what I believe it shouldn't be able to move, should I replace the distributor or no??
