Running Lean

[borodaz]

well had my engine/tsc/vsc lights appear, taken it to garage and code says its running lean the garage said, anybody have any idea why it would run lean ?

car is due a service, could it be my air filter ? my typhoon filter was red when i purchased but now it is black , dont know if this is normal and it just needs a clean but could it be causing my car to think its running lean ?
