LS2 will run on 1 O2 sensor
Sunday I learned the hard way that the car will run fine with only 1 O2 sensor.
I have a wide band with narrow band simulation in the left bank. Sunday my AFR gauge was acting up. Eventually the CEL came on but the car ran fine.
Turns out my buddy who was with me must have stretched out(big guy) put pressure on my WB O2 controller under the floor board where the Audio amp is. Plugged everything back in and the WB started working again.
I always wondered if I would be SOL if the WB ever failed on me. Now I know.

Car will run fine. Remember, the O2 sensor just senses how much exhaust is coming out of the engine. In theory, one the exhaust stage of an engine cycle is complete, there is no more issues with the functionality (if that makes sense). Unless you are running turbos or have a clogged cat, performance shouldnt be an issue.

I've always told people to not set it up like this.. yes, it will run, but it's really not ideal IMO
Mine ran like **** and would barely stay running when it happened on mine, so I got rid of that setup and just added another bung

So are you running your 2 rear sensors and the wideband?
