Back from the shop

It a code on both banks, it popped up a day after I brought her home. I don’t have a snapshot of when it happened. I was data logging when the code was thrown though.
 
I did the cigar smoke test and no leaks. I did however find a clamp that was way up on a hose so I moved that back in a better position and placed the PCV pipe in the air inlet plumbing a little better, there was obvious oil spray on the pipe. Cleared the codes and we'll see if they come back.
Cigar? Cigarette? Moxibustion? Charcoal? Old underware soaked in gas, lit and blown out?
 
Drive to work today, no CEL, but LTFT are around -15%. So no fix. I’m going to compare this data to previous data to see if the MAF is different.
