2011 Cruze Eco P0449 Error code

A while back I had a P0449 error code on my 2011 Eco with 70K miles- and I've replaced the solenoid at the charcoal canister and the one off the side of the head- both old ones tested good and I'm running to a "What's next" issue. I'm wondering if I need to take this into the dealer for a smoke test.

Anyone have any experience with this one? I can clear the code and next time I restart the car it comes back.

Clarification I did the evap vent solenoid & purge valve, all parts are AC Delco I think from amazon if I recall.

I also replace the gas cap with a Chevrolet new one too.
