Re: Help with rough idle and acceleration - TIA
How could they be in series????? That's like +-+-. You think it's
wired to go though only one plug and out through the ground or something
and back through the other plug, and to what?

Right Jerry, almost. :-)
The cylinder on compression stroke has a higher voltage demand since it has to
overcome cylinder pressure and the hydrocarbons. This is easily seen using an
oscilloscope.

Re: Help with rough idle and acceleration - TIA
You finally got it! That's exactly how it works.
Hook your oscilloscope up to the positively fired cylinder and you will see an
inverted pattern.
