Broken valve spring, vid inside.
The spring gremlin got me. I was planning to swap them out around 80k miles. I have 79,313 when on let go. So, I am posting for those that have not done it. I got lucky and the valve did not drop, maybe you won't. Swap them out. You get OEM set for $80 shipped. Get compressor tool and look at online tutorials to swap them out.

Mine wouldn't even run without basically flooring the throttle to start it and goosing it hard every second. Took awhile to diagnose since it wasn't actually throwing any codes, which I still find nearly unbelievable given how badly it was running. Guess the sensor patterns didn't fit any prerequisite codes.

So glad the spring stayed under the retainer.

shut the engine off immediately. I ran mine with a broken valve spring trying to "diagnose" before i knew it was a valve spring, and it dropped a valve, broke a piston, wedged the rod against the block wall and blew a hole in an IRON block. your aluminum block will surely fare worse. I can't believe anybody would run it like that
