[Diy_efi] false myths

[Phil Lamovie]

I don't know where you got this info from but it's not fair to post unreliable
answers to reasonable questions.

"AFAIC, misfire from too lean an A/F mixture, is a false myth.  In reality,
continual leaning can be conducted until which time, the combustion flame,
due to a lack of heat, just goes out.  Sorta like turning down the gas valve
on a kitchen range, less and less heat (not more) is generated until the
flame, from a lack of fuel finally goes out.  The misdiagnosed so labeled
'misfire' is actually the result of the flame in one or more cylinders going
out ahead of the others, due to the normal lack of a precise equal AFR
in all cylinders.  The physical appearance/feeling of a misfire, is actually
in reality, one or more cylinders going dead, no different than if a plug
suddenly stopped firing."

There are so many holes in this paragraph that it would take far too much time
to go through them all suffice to say that if you wish to help please be sure
of your physics before you add to the general level of confusion.
