[V8] Slight acceleration issue

Egad.  The dreaded (and very ubiquitous) surge condition.  Repair
patches are varied, including FPR, O2 sensor, plugs, and vacuum hose
replacement.  I recall one instance of claimed repair after replacing
the t-stat.  There's also TPS, MAF, and other high dollar crap shoots
with low likelihood of fixing it.

There's gobs of intel in the archives ("surge").  The first 4 items are
the place to start.  On my car I basically replaced everything and it's
now only slightly there, if at all.   Or maybe I just fixed it by using
WOT everywhere.
