im working on a ford focus with the same code. lean condition can be one of two main concepts. 1. either not enough fuel is being put into the combustion chamber or 2. you are not getting any or complete enough combustion in one or more cylinders meaning a miss fire.

1. can include fuel pressure so:
fuel pump
injectors/rail are bad or clogged
fuel filter clogged
fuel leak(not likely)
also can be vacuum leak: check for these at all hoses for the vacuum system.

2. o2 sensors only look for oxygen presence so even if you get fuel but its not burning youre gonna get too much air hence lean condition.

have you tried a tuneup:
cap
rotor
wires
plugs

run a bottle of cleaner through you fuel tank. seafoam would be best or you can use injector cleaner.

hope this helps. sorry if im wrong or missed something its very late lol. oh and look into the egr system i believe this can cause trouble too!

hmm. have you had any other major maintenance done recently like timing belt, etc?

is the car getting adequate fuel pressure? check your coolant, does it look normal? try a compression test. are you absolutely sure the EGR system is clean and operating correctly?

how about your PCV valve?
the engine run really rough? like almost as though theres a miss?
