Well, I got the green light on the 02 sensor replacement outcome. I decided to go for breakfast at a favorite place about 20 or so miles from where I reside. I had the cpu reset and ventured out. Before I would have the nasty check engine light resurface at about 10 or so miles on the road. Yesterday, going there and back I didn't get a return on the little icon glowing, lol!! It's the only issue I have encountered with it. It's always been garage kept & with 40K actual miles on it...it's just like new yet. I don't need it much anymore, and have been pondering on maybe selling it. It still shows to be worth a nice pocket of coin.
