I'm trying to think of a reason that would prevent me from setting up my own cylinder deactivation mode with a switch.

To me it seems that all you would need to do would be to setup a switch that would cut spark at the spark plug wires and cut the electricity to the fuel injectors. You'd have to think about which cylinders to cut to keep the engine balanced but that would be easy.

Am I missing something here? The only problem that I could see with this is that it might trip the 02 sensor out, half of the cylinders would be pumping atmosphere out the exhaust. But that's the only problem I could see with this. It wouldn't trip the knock sensors out... Am I crazy?
