    I have a 2004 Columbia 12.7 13spd. When I turn right the engine sounds like a detonation knock/ping. The sound only happens when I turn right, going straight or turning left it doesnt make the sound. I can duplicate the sound everytime by turning right. Any help would be appreciated.

    One of the motor mounts might be broken

    Most likely the right side too. Probably allowing the motor to rock to the left

    Hate to sound like a smart### but are you sure the nock is coming from the engine? Have you done a oil sample sense this started

    Just guessing could one of the wires to the injector be losing contact when turning right Or something in the wiring harness????
