If you run your rig with a bad knock sensor the computer will not be able to tell if or when your engine starts to knock (such as a rod knocking). That is if it isn't already cause the sensor is there for insurance. Make sure the sensor is bad and if so have it replaced asap. It is an expensive job cause you have to remove the intake to get to them (some engines have two under the intake). willyray3
