5+ yrs ago bought a Yukon and all eight of my plugs looked much worse (see pic). My piston rings were stuck in their piston grove. I did Technical Service Bulletin TSB 10-06-01-008M.P0307 and stability track errors are back…
my plugs and wires have ~20k on them.
Also getting the attached p0899 error

Installed catch can, AFM deflector, valve cover, did piston/combustion chamber soak. Oil consumption immediately went away and stayed away.
