Had my 08 Silverado throw codes 0499 and 0496, after everything I read I was thinking it would be a simple Purge Solenoid replacement, but I took it to the dealer for a accurate diagnosis, and they said I had my "Evap Valve Stuck Open" They advised I would need that replaced as well as the harness. The total project including the smoke test would end up costing me about 490. Is this something that can be done without a shop doing it? Is it worth taking somewhere else and not the dealership? Any info is helpful. Thanks
