MasterWith so many codes, I would check to see if the purge valve is flowing, then check the vent valve and then see if the canister is flooded with fuel, in that order. This is Emissions Diagnosis, I do this in CA and it takes some skill and some training, or you will end up replacing parts that are expensive and not the problem.
