    Misfiring cylinder..."most likely" suspect is one of the 8 coils over each spark plug... C.O.P. ignition...(coil on plug) see mechanic to find out which one and suggested repair! Due to the nature of this engine for spark plug removal proceedure, plug replacement is NOT diy! And it needs that too!
