Thanks, Tim and George.

I checked Courtesy's website, and they list 2 wiresets for the 1991-1994
SR20DE engines.  One is for "8/90 through 3/92" (P/N 22450-890392).  The other
is for "4/92+" (P/N 22450-0492) -- I don't remeber there being a difference,
but this is my first wireset for my 1993 (made in 12/92).  Could this be a
misprint in the dates intended by Courtesy to differentiate between high-port
and low-port?  Or was there really a change in the mid-1992 production time
period which would require different wiresets?

And as usual, he was right.  The ones in question were Nology wires.
It seems that they produce some RF interference that gets picked up by the
computer's wiring.
