Hello and welcome to JustAnswer!You have a couple different issues going on. The evap codes are for a medium and large leak, which could be the gas cap, a leak in the canister or other component, or a leaking line.The misfire codes may be caused by a number of things depending on when it happens and what has been done, it may be as simple as spark plugs.What year and model is the vehicle and what engine do you have?Has anything been done to try to repair the issues?
