  1. 3800 Knock sensor

    Naturally Aspirated
    swapping 2000 lesabre 3800 into a 2004 lesabre. Somehow the rear knock sensor was missing in the swapped engine. Can an engine run efficiently with one knock sensor and can I simply plug/seal(screw) the rear one. It looks like the plug for the rear sensor was not connected anyway. Looks like it...
