My check engine came on with these codes and i'm wondering what i should fix or try. the car seems to use a lot of gas lately and runs kind of rough, any help would mean a lot. thanks

hi could u tell me wat type of engine it is

Ok, i've got:

P0171 fuel injection system lean (which may be caused by next fault)

P1130 Air/fuel ratio sensor or range performance fault.

At this point, i'd have gone for most likely thing to be the lambda sensor. But, I hear this can be thrown by other things.
