Default You can look for

fault codes (don't have the exact code #'s) stating that cylinder bank 'x' is running lean/rich

That's the most common one with a bad maf

Default engine -> basic settings -> block 002

do this while the engine is running and at operating temps (coolant >= 80 degrees C)

the fourth column should be greater than 3.0 and less than 4.5 or something like that. i can get the exact numbers later today. if someone has a bentley cd handy, maybe you could help me out here.
