2nd set of O2 sensors
I found another set of O2 (or at least they look like) sensors behind my catylitic convertors. There is a set just off of the exhaust manifolds that are wired to the ECM. The last set behind the convertors are wired together, but they don't seem to be wired to anything else. What are these for?
