DTC P1151 is a lack of switch on the front left hand O2 sensor.
I personally would have been surprised if replacing the fuel filter fixed a P1151 and EVAP P1443.
In some ways, the P1151 is one of the hardest to fix because the list of POSSIBLE causes is sooooo long.
Trouble shooting has to begin with a through look for vacuum and exhaust leaks. Focus FIRST on the spots that can affect the left side of the motor. Value cover gaskets, oil dip stick, PVC breather line. Exhaust leaks on the left side especially from the EGR system.
The move onto to anywhere else unmetered air can enter. Don't cut corners. Even a tiny vacuum leak can cause issues.
Check ALL hoses for leaks and loose fittings.
Since you have an EVAP problem at the same time, pay SPECIAL attention to the EVAP gas vapor line from the throttle body. Gas vapors are hard on rubber parts. Frequently these hoses rot from the inside out. Touching an EVAP hose will leave tons of black deposits on your hands.
This information has already been given once. Now it time to roll up your sleeves and get under the covers a little bit more. A DTC P1151 isn't going to give itself up for just a fuel filter. The car gods demand a bigger sacrifice.
