2021 4Runner dieselish sound 1500rpm when cold especially throttle up to 1500 a and let of throttle. Read articles about how 1GR-FE engines are noisy with dual VVTi BUT using Think Car it shows long term fuel trim bank 1 @ 2.3% and bank 2 @ 5.4% no fault codes. Had rotten egg smell once with back window down. Still under warranty is this normal or time to visit the dealer? Scotty Kilmer did a video about a year ago on another 5th gen 4runner with similar issue curious if he's had any followup or anyone else have any feedback on this?
Thanks!

If it's under warranty, get it fixed.
