No.  I am saying it might be injecting little or no fuel.  Then the attendant
cylinder becomes merely an air pump.  This leans the exhaust to the point
that the control system tries to compensate with a very rich setting which
cannot possibly be completely burned in the other three cylinders.  I had
this happen once at night.  When I finally limped home, in the darkness of my
driveway, I could see the cat glowing cherry red.  It was so hot, I called
the kids out to have a weenie roast.
