Is this what your diagnostic computer is telling you? Computers don't know everything. Only experience can ensure that you'll troubleshoot effectively. Chances are that there is a vaccum leak. Check the EGR valve. Also check the vaccum lines. You may have clogged injectors on one side as well.

Agree vacuum leak somwhere
The fact that both banks are indicating lean is significant.
If it were an injector it would be one side or the other.
So to be lean 1 and 2 that means a common leak to the
whole engine somwhere. Like something leading to the intake.

if both banks are running lean, usually 1 or 2 things that could be wrong:
1) fuel filter is clogged and needs replacing
2)both oxygen sensors need replacing, bank 1 being the one in the exhaust manifold and bank 2 being the one before the catalytic converter under the car
stop by a local parts store, shop, or dealer and clear out codes
try step 1 first (cheapest and easiet), drive it

2 cars showing lean... both yours?
The focus won't run lean bank 2.. no bank 2
would have to see first what it is, but first question.... Tank up on e85 ethernol which is cheaper?!?!?!?!?!?!?!?! If you did, there is your problem.... e85 cause lean codes in Fords that are NOT FFV!!!!!!!!!!!!!!!!!!!
if not check for a vacum leak..probably the PCV line from PCV to engine.
