Just an observation - the O2 sensor is monitoring the exhaust in the manifold, and without the injector firing it will read an excess of oxygen and try to richen the mixture. I cannot imagine how this will save fuel or improve mileage especially with only one dead cylinder unbalancing the firing pattern.
