No, when the voltage goes high you have too little O2 in the exhaust, so it
leans the mixture to compensate. When the voltage goes too high you have too
much O2, so it richens the mixture. A missfire allows O2 to flow through
unburned, and forces the engine rich. From my understanding and experience
anyway. Been wrong before - but I think I got it right this time.>
