I got a 2017 citadel with 5.7. Got the emissions code. Replaced hoses, the module, the charcoal canister. Still getting the code. Last thing I hear is the gass tank fill neck. It would make sense because ever since we had the truck, we've had to fill the tank with the pump handle upside-down.
Having a hard time finding the parts and a replacement video. Anyone has done this that might point me to a good source of info?
Thanks,
