Car runs great any time except the first start after filling up with gas. It will idle poorly for a minute or two after filling up. I have read that it is likely an issue with the EVAP system. I'm not sure if I should be looking at the fuel separator (F2GZ-9D289-A) under the hood or the EVAP canister at the fuel tank. There have not been any codes from the cpu yet, but I would like to get this resolved. Any help on this would be great!
