[s-cars] Low boost revisited

[Robert Myers]

Hi again Y'all,

Let's see...  How do I put the best spin on this?  Ah, yeah, that's it.

My RS2ed urS6 has been showing intermittent low boost.  (10-14 psig 
or so vs the 25-28 or so it should have been having)  Suspecting that 
my original WGFV may have been sticking I pulled the device and 
sprayed its innards with Kroil and reinstalled it.  I <ahem> 
intentionally left the wiring harness plug disconnected.  (Yeah - 
right - that's it.  Duh.  :-( )  This left the car in a "permanent 
vegetative state" and lousy boost for my entire Saturday business 
trip.  Plugging the WGFV connector back in this morning gives what 
appeared to be normal boost (28 psig max) again for about 80% of a 
test drive.  Then, suddenly, without my input boost dropped back to 
the 12-14 psig level and would not go above that level again during 
the drive.  It looks like maybe the Kroil treatment accomplished 
nothing.  Oh well.  It was worth a try.

One additional observation.  At one point in my test run my boost 
gauge briefly showed over 30 psig and I hit the overboost 
limit.  Nasty feeling.  :-(  WGFV stuck open rather than closed this 
time?  A new WGFV is on its way here.

Teddy is reporting that replacing his OXS made a difference with his 
apparently identical problem.  Since my OXS is, AFAIK, the original 
one and has 87K miles on it I'll replace it just on the off chance it 
might actually help and, besides, its probably about due for 
replacement anyway.
