Engine leaning more after refueling?
Motor Vehicle Maintenance & Repair Asked by Student677 on March 10, 2021
Corolla with intermittent code saying System Too Lean (Bank 1) P0171 after refueling. First i noticed that there is slightly stronger fumes when i refuel then the code will illuminate ( Code not always comes on). It happens with half tank and up and always improves with lower than third of tank. I never top off and i just replaced gas cap but didn’t help. I read here a lot and checked Fuel trims and found they go higher positive every time i refuel. I have some data file to share Here Please help.
Thank you in advance.

Have you checked the fuel tank filler neck? It can deteriorate on the Corollas and cause the issue you describe. See this link for a picture.
