If you have just the one O2 sensor controlling all the cylinders, won't the injectors still be squirting fuel into the deactivated cylinders, just less of it? Wouldn't this would cause the active cylinders to run lean?
Should you not have the computer cut fuel & spark to individual cylinders on a rotating basis?
