I have a check engine light on as well, but its intermittent.
P0172 - System Too Rich Bank 1
Sounds like that could be a multitude of things causing that one so this will be fun: https://mazdamanuals.com.au/wsm-secure/WSM/D9G6-1A-21B_Ver17/esicont/srvc/html/id0102h9934300.html
Hope its just a MAF or O2 sensor.

The one thing this lexus doesn't have is a check engine light.

My 2013 Hyundai Accent I bought in 2014 had a CEL for about 3 years until 2019.... when that dash light burned out.
Better than it being lean I suppose. That said, I'd normally suggest a fuel injector cleaner but a lot of modern motors don't play nice with it.

I already ran a bottle through. Direct Injection though so not sure it does much of anything anyway. Also usually try to use Top Tier gas.
I did notice the stronger gas smell, so something definitely off.

Only difference with DI is that it bypasses the valves getting cleaned but the injectors should still benefit. Hopefully like you said it's just a bad MAF (can you clean yours?). With direct injection it's good to get carbon clean up done too if you haven't - look into BG44K - a lot of dealers offer it assuming you are still under warranty. My GF's 2021 Miata with the Skyactive 2.0 definitely benefited from it and she doesn't even have 50k miles on it.

Yeah the BG 44k is what I ran through the gas tank. I am at 135k miles now so probably could use a carbon clean up.
Yep, MAF sensor can be removed pretty easily. May try cleaning it and see what happens before I go down the rabbit hole of replacing parts one by one.
Oh...how do you like the 2021 Miata? One of these years when I have "fun car" spending money, I would love to get an ND Miata. I really like the looks.

Yea, at that mileage a carbon cleanup will definitely help. It helped every Direct Injection car I've driver or seen it done on. Both Mazda's with the 2.0 (her prior Mazda 3 before she upgraded to the Miata) ran much smoother after. My Accent the 1.6GDI also ran better after.
As far as the Miata goes, it's a big upgrade over old models as it actually can move out of it's own way now, at least the ND2 variant with 181hp. 0-60 in mid 5's or so and it handles like a go kart. Downside is she bought an automatic but it's still a fun car. Gas mileage is stellar too which is mostly down to it weighing 2300lbs.

Mine doesn't have one either, even after leaving it sitting for 10 years.
