THIS LOW RESOLUTION 02 SENSOR WAVEFORM
is showing pronounced consistant MISFIRE
====================
yes
that NOX graph agrees with my SWAG
but
it is true that combustion temperatures are HIGH during hi load with slightly rich conditions , when NOX output is very low, perhaps because there is no 02 availible to combine with the N
to form
NOX , during rich condition.
