my car is running lean in bank 1 and 2. never had this code before does it have to do with the o2 sensors or is it something else.

It's unlikely both of your O2s would go bad at the same time. Get a fuel pressure gauge and check your fuel pressure at the rail. Sounds to me like your fuel pump may be going out, causing a lean condition.

It could also be a MAF problem, but it is most likely to do with fuel pressure when both codes are set like that.

i read the codes and the 2 codes that came up are PO174 bank 2 running lean.

i did research and people say its either the maf, fuel filter clogged or fuel pump.

im going to put in my walbro 255 pump that i had in my formula and change the fuel filter and see if that solves the problem
