[V8] Sensor Question

[Justin Bowers]

I'll add in my $.02 and share that I swapped out both at the same time as it
hardly seemed worth the hassle of having to do a second time down the road
(likely sooner then later).  By the way, when I owned two V8's it was the
same for both.

If you can manage the spend, doing both at once is money well spent in my
opinion.

Replacing those sensors is such a PITA procedure that I would do both at
the same time.  As a matter of fact, that's exactly what I did when I was
having the warm start issue.  You have to extract both to get one out
anyway.  Like Steve notes, if one's gone, the other most likely won't be
far behind and the failure problem with the other is no go at all, as
opposed to delayed starting when warm.
