I figured I needed to check the MAFs and get these cleaned with the proper cleaner which I did and so far so good... the permanent error is gone and so is the engine light now...

Long story short I also as of today did spark plugs and coils myself - was fun!

So far so good!!

I'll post back if anything changes.

Just curious, how hard was it too install the rear oxygen sensor? Any photo like you had for the front? It seems like the running rich or lean problems can take some time to sort out.
