    Help to fix codes P1D73 and P0456

    So I tried fixing them before but I guess no luck with a complete fix as these codes appear again. I got a new gas cap and the evap leak detection that's by the gas tank but I still get this code. And for the P1d73 I found that it could be the grill shutters which was true they were not aligned...
