A diagnostic method for a reciprocating internal combustion engine with multiple cylinders includes determining a first exhaust gas percentage in an exhaust stream of the engine while cutting a fuel supply to a first cylinder of the multiple cylinders and fueling the remainder of the multiple cylinders. The method also includes determining a second exhaust gas percentage in the exhaust stream while cutting a fuel supply to a second cylinder of the multiple cylinders and fueling the remainder of the multiple cylinders, and determining a diagnostic condition of the engine as a function of the first exhaust gas percentage and the second exhaust gas percentage.
