[V8] mixture adaptation/idle issue

[Coleman, David]

That's some sort of OXS code.  You went to the dealer to have them tell
you that?  What'd that cost?  And what home-job codes did you get
beforehand?

I don't remember where this thread left off, but unless there's some
obvious problem elsewhere, unplugging or replacing the OXS is a standard
first stop for an idle/running issue.  Once that's done, you'll start
down the old road of fuel pressure regulator swap (recommended every
couple years I think) and cleaning/replacing the idle stabilizer and
throttle position sensor.  Had you washed the car or driven through a
massive downpour recently?
