fireing order for 2000 2.5

[wchafee]

I have installed a hydrogen generator and I need to know how to retard the timing. Which plug fires first or is it simultaneous?

Wait - What are you trying to do. Why do you need to retard the timing? That's computer controlled, you changing the firing order does not seem to me like a good idea. you'll set enough codes and check engine lights to light up a christmas tree, killing any chance of gaining mileage from a hydrogen booster.

What are you thinking of trying to do?

since hho burns more rapidly than pure gas, retarding the timeing should make it run more like it was meant to.
