if the knock sensor was retarding timing this would cause all you mentioned as well as running hotter.....these sensors are to be sealed on both ends of intake manifold where i believe they are mounted on your engine, under intake , this is how they get damaged...by the lack of a good seal allowing corrosives to enter...
