Ok because car is buried in a garage right now.
I'll try loading an alternate tune tonight.

Yeah, I realized there was some fine "debris" from grass in my airbox and filter.Pull your MAF and clean it. A dirty MAF will cause high STFT readings. It's easy enough to do and definitely can't hurt.
Did you check for vacuum leaks on the bank that's showing high STFT?Swapped and then reloaded tune. Learn flag was at 0 and I wasn't able to take it for a drive/top-off yet. It was still running rough and same exhaust smell in the garage.
Anyone know the part numbers for the O2 sensors?
Any way that this is being caused by some catastrophic thing like compression loss? valve/timing issue?
I would think if those were a possibility, then the CEL/DTC would be apparent.
I've checked all vacuum lines. Didnt spray anything though.Did you check for vacuum leaks on the bank that's showing high STFT?
Yeah they areLog the O2 readings on both banks and compare. They should be about the same. 1.00 lambda at idle, give or take a couple hundredths.
Do they stay consistent while cruising? If so and they are both reading then I wouldn't think it is a bad o2, possibly one lazy but it should show a different reading.Yeah they are
