My 1998 ford exp 5.4L is running ruff and misfiring code are p075,p0136, p0156, p0171,p0174, p01131 &p01151
I have codes 172 & 175 (Fuel trim bank 1 & 2, running to rich) So I was told to replace the Mass Air Flow Sensor. Easy install but very expensive ($150). We'll see if the service engine light comes back on.
Look for vacuum leaks the last 4 codes are lean codes
primarily lookm at the pcv hose noturious for collapsing
System Too Lean (Bank 2)
Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.
Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.

Thanks.
