Non working O2 sensors Hi,I am little stuck here and would appreciate any help for my 76 nova LS6/A4Recently changed exhaust over to long tube headers. Since this change neither O2 sensor is working.Voltage just sits there At .447 volt for the right bank and at .887 for the left bank.I changed both sensors,no change.Verified signal circuit wiring continuity from ecm to both sensors.also verified heater circuits.Any suggestions.Thanks,JC.
