Hey, Jeep fam! My '15 Grand Cherokee has been idling rough, and now I’m seeing the PO174 code, which from what I understand means it's running lean (bank 2). I checked for vacuum leaks but couldn’t find anything obvious. Could it be the fuel injectors or MAF sensor? Anyone dealt with this before? Don’t really wanna mess up the engine. Appreciate any advice!
