Well, my dad, who recently got into saving gas, after reading about multi-displacement engines, suggested that if we remove the power wire to one of the fuel injectors on his V6 Nissan Quest, that it should use less gas as it is now only effectively a 2.5 liter engine, and thus can save gas, while cruising at least. Obviously, I am not sure if this works, we do not have a SG or SGII and have no way of seeing if less gas is actually used or if mileage goes up, on a short run. We tried this yesterday during a short drive, and it was a little rough in gear while stopped, but above about 1200 rpm or so, the engine didn't seem to run roughly. It also idled normally (in park and neutral). Has anyone experimented with this before? Do you think it might damage the engine in some way?
