Ok guys, first post and it's about P0449. Sorry... I did a search and have come up with many different issues it could be.
This is the situation...
2008 Silverado Z71 5.3
Check engine and Auto Zone says P0449 and to get a new gas cap. That didn't help at all and that's when I started looking here. I also have trouble putting gas in the truck. The gas backs up and the nozzle clicks off. have to pump really slow.
Also, what can I get to read/clear these codes myself? Is it possible to get a programmer/code reader?
Thanks for any help y'all can give me. -Sikes
