This is a problem with the EVAP system. You need to have a smoke test done to find out exactly where the EVAP system is leaking and repair it. Some leaks are too small to be seen with the naked eye. With an EVAP trouble code the gas cap is always the go to fix which, unfortunately, usually doesn't fix the problem. If your shop doesn't have a smoke machine, visit a shop that does. Hope that helps! Jim

You probably have another leak in the EVAP system.
