Its a 1998 model and a 5.4l moto. Im going to ford and gonna have the error code tomorrow...
I've read that the fuel pumps are not that good, so i was thinking to take a fuel pressure test.

Most likely failing O2 sensors. Those cause lean fuel mixture readings. Bank 2 I think is the passenger side but not 100%

bank 2 is the drivers side


best way to remember is bank 1 is always the side with the #1 cyl
