Default passenger side even cylinders running rich... old plugs on that side only black

passenger side plugs came out sooty and black and it was all 4 of the even cylinders.... i did previously have a misfire going on on 8 but that is resolved. also when i had my ignition coils off all the odd cylinder posts on the coils looked nice and shiny where as the even ones looked as though they had been burnt by the heat from the ignition circuit to the plug.. it was really weird

Sounds like a bad O2 sensor.
O2 sensors are what tells the ECU how much fuel is being used on that bank.

Yup. You may want to call a local indy shop to have your adaptive memory erased so it will read the new sensors sooner.
