    the first step is to know what codes you have, otherwise
    you are diagnosing the problem by throwing parts at it.
    my guess is a misfire; but you gotta know what cylinder.
    was it something he did?? no way of knowing that; however, this is NOT an easy do-it-yourself car.

    this is coil-over-plug, so there are no spark plug wires
