it would clear out any gummy deposits from the fuel. These deposits would lower fuel pressure at the injectors just like a clogged fuel filter. I suppose lower fuel pressure would cause the engine to sorta run lean (raising combustion temps causing the NOX problem) because the fuel isn't getting atomized properly.
Were you getting any other high combustion temp symptoms? I replaced the O2 sensor (along with plugs and distro cap) which cleared up some weird temp problems.
