Hi all , so my nice new to me car has started to how it’s problems, a leaky headlight a leaky roof a dead viscous fan, and now I noticed the engine management light doesn’t ever illuminate. Curious I plugged the scanner in and I get the above codes - has anyone had this combination before and where do I start on a 4.2 s/c?

Cheers Current stable:
2006 BMW M6
2007 4.2 V8 S/C FF
Gone:
2002 4.4 V8 FF

Bank one is running lean.
So way to much air and to little fuel.
So Ill should start with map or maf sensors and than injectors.
