[V8] mixture adaptation/idle issue

[John Dodd]

It did not cost anything for the codes.
The code I got was 2413.
I changed the OXS and FP regulator about 15 000 km ago.(3 years ago)
Did not wash the engine or drove through rain.
I did clean the ISV valve but not the TPS.

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?
