[s-cars] Still chasing the hiccup

[brian hoeft]

I haven't been following this Wylie. At first glance it sounds ignition
related. If you un-plug the N75 you will not hold as much boost, but no CEL
or other driveability issues, other than your neutered ability to merge on
the highway or the like. All that would do is tell you is that it doesnt
work when its un-plugged. Sorry, no whitty analogy right now..

*           Groundhog Day 2011*
This year, both Groundhog Day and the State of the Union address occur on
the same day.
"It is an ironic juxtaposition of events: one involves a meaningless ritual
in which we look to a creature of little intelligence for prognostication
while the other involves a groundhog." -A.A.
