Hello to all. I need help with my LSx o2 sensors. As I look at the scan gauge on my LSx swap, I noticed that my O2 sensors aren't responding to the PCM. My exhaust Is open due to the fact that I was rejected by the muffler shop due to leaking gas from the fuel sending unit. The loose AN fittings was tightened, fixed. Is there any reason why the 02 sensors are dead? I would hate to buy new sensors and not Resolve the issue. Thanks in advance, Clark. I did the harness myself.
