Default LTFT's not close to each other. Also only using 3 fuel cells

What would cause the bank 1 LTFT to be -1.8% and the bank 2 LTFT to be +7.8%?? Could it be a bad O2 sensor? I have been getting a non switching code in the AM 5-10 minutes after a cold start on bank 2.

Secondly, the last 3 days I have been Atapping on the way to and from work. The only fuel cells being used are 20 (At Idle) / 21 (below 12% throttle) / and 22 (above 12% throttle).. What would cause that?

Last thing for now, Is there a real difference between O2 sensors besides the part number and the price?

Current mods: FTRA, Filter, Lid, MAF ends, MAFT, Ported TB, Long tube headers. MAFT is set at 20% rich right now. Thanks in advance.

Seems like your one side is sleepy from being too
cold. More heat makes a faster, happier sensor.

The vents on the passanger side O2 were crushed when it was screwed in to the headers. When the headers were Jet Hot coated there was excess material in the whole.

Pulled the O2 sensor, opened it up with a round file, dropped in an extra O2 I had and walla. LTFT's are equal, uses all trim cells, no codes and runs a lot better.
