Quick question:
Generally speaking, on a V6 with 2 upstream and 2 downstream O2 sensors, does the PCM adjust the AFR of each bank independently based on values from their respective upstream 02 sensor, or does the PCM adjust the AFR of both banks together with combined values of the two upstream O2 sensors?
Curious is all.
