Best answer
P0172 System too rich Bank 1

This year make and model will not have a fuel pressure sensor , If you fill up the tank and a misfire condition along with a P0172 occurs you would have a problem with the EVAP canister vent control system , Fuel would enter into the EVAP canister and during its purge cycle raw fuel would enter into the intake system,
