    Default Emission vent valve code p0449

    Hi This the 3rd valve I will have put in the truck and I cannot remember the one that i got At advanced auto which fit my truck 2006 silverado 1500 4wd. The chevy dealer was way out of the park for this part and I believe I only spent around 30.00 for the same part at advanced auto and is only a five minute job to replace. The one that matched mine was I think off a blazer,I need help?
