Default Friend in Need!

My friend has a 2001 Z-28 A4. He's getting an SES light, and we need help.

The light goes off when he fills up, then come back on 10-15 miles later. He had it scanned (Don't remember the exact codes) and it said that both banks were lean, and he had a "mass-volume-something" (He couldn't remember, I know it would help if I knew exactly what the codes were)

What could cause this? Our first thoughts were fuel filter and O2 sensors? We're gonna change these ASAP!

Is there anything else we might look at to help this?

Thanks in advance, if you need any more info, please ask, I know just about everything about his car!

Taco

Yes, he had bought a 85 MM SLP, but I have it now, and he has MY stock MAF (99 WS-6 MAF) on his car. Would that cause the problem???

Thanks again!

He reminded me last night that the MAF and TB are ported, if that makes a difference.

Any other ideas???

Thanks!

TB no effect.
