Can issues in Bank 2 cause code in Bank 1?
I have a "too lean Bank 1 code (PO171)".
I have looked for exhaust/intake leaks, replaced the O2, found and fixed some PVC leaks, re-checked the plug wires on Bank 1 (driver side). I am still getting PO171, however.
Can issues (e.g., a bad plug wire, exhaust leak, or bad O2 sensor) in Bank 2 casue a PO171 too lean code in Bank 1?
Thanks????

No, I have not swapped Bank 1 and Bank 2 fuel injectors or measured the fuel pressures at the rails.
Question: If the O2 sensor in Bank 2 was providing faulty readings would the PCM adjust the F/A ratio and make Bank 1 run too lean?
