vsc trck off dilemma

I had my engine and vsc/trac off lights on, plus engine light, not blinking. Codes read lean condition bank two and the forward O2 sensors showed. Changed the sensors: no improvement. My mechanic wanted to hunt around not really clear what to do: maybe we should do a tune up? Plugs had plenty of miles on them. Maybe a vacuum leak: check by eye and saw nothing and the car ran smoothly, etc.
I was about to go to the dealer but the thought of their bill prompted me to continue to explore.
On a lark, I changed the gas cap, no change.
I changed the MAF sensor, which I am told should be replaced at 60K; I have 257K...lol! I believe the engine light cleared after that but not the other lights.
There was a whole youtube video with a guy diagnosing a similar problem, spent a few hours and ended up replacing MAF sensor: bingo, worked for him. That's why I did it.
My VSC and Track off lights still remained lit if the car was in motion. No lights if at idle, just as soon as it moved....lights on.
I saw another video about the zero point calibration and yaw sensor issue. I just had a bad ball joint and control arm replaced. So, I did that and I've driven it a week, probably 100 miles and all lights remain off.
That's what did it for me. Hope it helps someone.
