[Shotimes] Re: Tale of 2 SHOs

[Mike]

California smog check, using dyno. The 90 has 156K, with a full 60K done on
the '90 about 10K miles ago.  It also has new EGR plumbing, 4-year old ShoShop
y-pipe/cats, and recent Bosch O2 sensors.  The car runs very strong, no
apparent problems.  I ran the '95 at 2K (rpm) for a couple minutes just prior
to the check.  It would appear that idling is not the best option.   The '95
is totally, completely OEM, original plugs, wires, everything, but only 59K
miles.
