    There is a service bulletin for the code p0449 setting on your 2007 Chevrolet Silverado 1500. The number is #09-06-04-028. The repair suggested is to replace the canister vent solenoid and relocate it to a position near the fuel filler neck. This may help but there is know way to tell for sure if this will correct your particular issue.
