That P0140 is troublesome, even if it didn't come back. Oxygen sensor codes tend to hover for a while in the pending queue before the CEL is set.
Those danged Bosch sensors react so fast they confound our PCM's with what look like trashy waveforms. They're accurate enough, strictly speaking, but our PCM's don't have what it takes to clean up those signals and makes sense of them. It might be worth swapping that critter out just to eliminate it from consideration.
