took my 2006 Nissan pathfinder to dealer they said my catalytic converters in bank 1 and bank 2 are bad
p0420 and p0430 are the codes
we just changed the cat in bank 1 not but a year ago if that
don't wanna put new ones in again until I find cause of failure
so I bought a obd2 meter to read live data on my o2 sensors
finding something interesting
any advice on this or cause would be appreciated
o2s11 reads slow fluctuation
o2s12 reads a constant 750 no movement with a n/a for %
o2s21 reads slow fluctuation
o2s22 reads fast fluctuation with a n/a for %
any help at all would be great before I shell out major cash to fix
