[edwin711]

Check engine came on today read P0174 system too lean (bank 2). Looked it up online. Gave me a list of things that could cause code.
- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

Have any of you encountered this issue?

Thanks in Advance
