120k miles, well cared for, automatic transmission.

Intermittently makes a knocking/tapping noise at low rpm under partial throttle. Most noticeable/repeatable when letting off the throttle entirely while coasting and then rolling back onto the throttle. Will make the noise for a second or two and then stop, 5-10 quick tap tap taps.

No codes, seems to otherwise drive fine. Noise not present at higher RPMs. Sounds like it's coming from the bottom of the engine but it's a subtle noise and hard to tell. I tried to take a video but it wasn't clearly audible.

Doesn't sound like wastegate rattle or rod knock to me. It's been doing it for ~2500 miles now. Pulled the oil filter and checked the oil and didn't see anything concerning.

Had a low fuel pressure code a bit before this. Replaced the pressure sensor and it hasn't returned.
