If my MAFS was bad would it throw a code?
Just like the title says...if my MAFS was bad would it throw a code? My car is running extremely rich all of a sudden for no apparent reason at idle and WOT. I did 2 things before this problem occured....I changed the plugs and cleaned the MAFS with Alcy.

There are MAF frequency high and low codes
that would be set if the MAF was runaway or
dead. But simply bent from cleaning accident
might just leave you with a bad mixture and no
code. Some codes relating to mixture faults can
take a day or two to show up.

The rich code is what I saw when I was messing
with my 85mm MAF tuning. But this was a natural
characteristic. I don't know how to restore a MAF
that's been messed up by cleaning. I think maybe
another cleaning shot, maybe with a friendlier
solvent (which alcohol? Rubbing alcohol has a lot
of water in it.). Also check that there's no foreign
matter on/in the sense coils and that none of them
are physically out-of-place or broken.
Maybe someone who's successfully cleaned their
MAF will chime in with chemicals used etc.
