After lots and lots of reading (I should be working) I've ordered a Bosch MAF, not the dealer one for $707, but one from parts store for $162. The dealer price of $707 is a little hard to swallow.

Seems my issues combined are pointing towards a failed or failing MAF. The ABS light along with the CEL codes certainly support this theory. I'll keep updates coming here.

Although the rodent or water theories carry a lot of merit. I'll start checking those as well.

Hey root,

Since you are in Seattle, next time you need OEM parts, talk to: http://www.****************************************************.com/

Pretty much everything I've ordered from them is half the price of Barrier. Last I checked Barrier charged 30% over the "list" price, and Sunset is way under list. Plus since they are in Oregon it only takes a day or two for stuff to show up UPS ground.

Thanks! It's been years since I've had a WorldPac account so this helps a lot.

I am using OBD-2 software which only has VW-Audi level codes beyond standard OBD2 codes.

Hooked it up, yup, all codes present, cleared them and ran a test on the O2's, they all passed.

I'll update when I get my MAF, re-clear codes and drive, log data.

Anyone have any other OBD2 software they could recomend?

New MAF installed today, cleared codes, 5 minutes into the drive they all came back.

Going to start looking deeper into the harnes.
