A thought.....
The first place air is measured is the Mass Air. I have had Mass Air sensors trigger both lean conditions and rich conditions. Just the other day, a Mercedes S430 gave me a rich bank 1 and rich bank 2. If anyone has the specs for the Mass Air, I would ohm out the Mass Air. If its telling the computer its getting more air than it really is, it will lean out the mixture to compensate.
