Will shorted O2 wires affect AFR in OL ?
Will shorted O2 wires affect AFR in OL ?

Shorted NBO2 wiring should cause the ECM to go into OL-Fault mode...
in any OL mode the active fueling table is the OLFA table (LS1B table B3605, LS1B COS table B3647).
It was just a question because i had a problem with completely different AFR in booth banks in OLSD LS1B car
No missfire in the car, all pistons are working and no exhaust leaks . injectors are flow tested and within 1% so i expect it could be a shorted O2 Sensor
problem suddenly happened but i still investigating about the reason
