I don't think this is correct; pumping those "dead" cylinders with the valves still working would draw tremendous amounts of energy; I thought the reason we just now were seeing this cyl deac. technology was that valves can now be opened via solenoids to let dead cylinders "breathe", or something involving variable valve timing. Of course, I may be talking out of my arse...
