	This only applied to those vehicles with the plastic intake manifolds.  I
don't think the backfire was ever a concern with the metal intakes.  One of
the conditions required for the backfire to occur was a very short cranking
cycle (a lot of people buying those BOP H and W-cars seem to think it
should only take only a half-second or so of cranking to start their car,
as well as thinking the interior trim should never rattle under any
conditions and they shouldn't be able to feel the torque converter clutch
come on).
