97 f150 4.2 liter manual transmission
I have a on going issue with my oil pressure gauge it fluttered so I replaced it and the problem seemed to go away .
so I thought it was just the sensor now it is doing it again since then I
have had a P1131: Ho2s diagnostic code circuit low variance bank 1 sensor 2
Does anyone know where I can get a listing of these codes or does ford even make them public? any and all help is greatly appreciated thanks

Hello jmknight and welcome to FTE. 
P1131 - Lack of switching, HO2S sensor indicates lean, Bank 1.
Check for intake vacuum leaks and/or exhaust leaks on the passenger side of the truck. Good luck!
