Hi guys I really hope you can help.

Our m272 keeps showing the 2 codes

P0746
P0750

Which is bank 1 and 2 too rich in fuel.

I take it too lean means vac or air leak and rich aomthing else?

I do have some scanners but can seem to find the correct reading for the lamber sensors etc.


Any one had these too rich codes?
