Updating my progress after this was installed... my continued to get engine light error but with the down stream sensor this time... I ended up ordering a second sensor for the same bank 2 but this sensor was specific for the downstream as the error noted...
After I replaced it the engine light went away for a while along with permanent error I was getting... however recently the engine light came back on with a "mixture too lean"... 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.
