[Diy_efi] Dead O2 sensor values

[kwsundell]

My pet PEEVE is spelling errors, but I don't generally make a big deal of
it.  I'll be running a sensor in each exhaust manifold collector, so I will
have two of them.  My question is, what type of readings do you get as the
sensor goes bad?

Depends.

My pet pive is folks relying on one sensor.
IMO, you need redundancy for total EFI control of anything.   If using a
feed back loop for AFR, then another totally independent sensor, and
feedback should be involved, as a double check.
