    It could be. But then again there could be 1 of 101 things wrong. Having the fault code(s) read out takes away all the guesswork, which at the moment is what you're doing.

    Fault code reader can't detect spark plug fault as they are not electronic. They can't detect compession either . It will be coil pack .

    Was the engine noisy at all mate, the chains are a week part of the 2.2, snapping or jumping a tooth or two is quite common.
