lol
anyway the charcoal canister issue is probably the cause of the smell
the maf won’t make the exhaust smell since the car has catalytic converters anyhow
*if your car is running stupid rich it could make the cats stink but you’d have other codes to indicate it
if you want to clean the maf as part of a preventive maintenance routine then go ahead if it isn’t the early KV maf

Might as well clean the MAF, see what happens. It's not like you're throwing an unneeded expensive part at it. I don't remember off hand what year your car is ( hard to remember everybody's car) but if it has the older AFM don't clean that.
I do agree with sdls about the canister could be causing the smell.

Can't do anything about charcoal canister. Can't find a new one anywhere and have been burned by 2 used ones.

The unit apparently use(?) activated charcoal and if disassembly/reassembly of housing is possible then swapping out the activated charcoal may offer a solution.
This topic deserves it's own post.
Another option is to look at Celsior configuration....

I wonder if State Emmissions Agencies give a pass if the part is unavailable from dealer...

No emission test after 25 year old vehicles in Ct.

The Celsior emissions system is not as complex as the LS400, nor does it appear to employ a charcoal canister.
There are fewer parts (hopefully not discontinued) that might be configured.
While this changes the emissions function, Toyota elected to discontinue a critical emission component at exactly the time when many are just beginning to fail.
So what is the solution?
