So I still have the speed limited to 120mph messages coming on.
Still having the check engine light coming on for lean banks 1 and 2.
Now I'm getting service lane departure system. And lane departure system unavailable.
Some rattle / scrape noise at certain engine speed and load conditions. Sounds exhaust related I think.
Had a lot of previous work done to it that you can read about in the "got codes" thread I had posted a while back.
