My buddy is having some problems with his CEL, it comes on every few weeks and these are the codes he's getting:
176 (M) Oxygen sensor not switching - system is or was lean Left or Front HO2S - Fuel control
543 (O) Fuel pump monitor circuit shows no power - Power / Fuel Pump Circuits
The car runs strong, it has a slight shake at idle though- It looks a little more than normal but I don't know much about the 5.0.
Can anyone tell me what these codes are typically pointing to? Fuel pump starting to go out perhaps?
