Hello everyone
this is my first post I own a 2003 Silverado 1500 w/ a V6 engine. I am experiencing a strong gas smell and I have a code that reads P0455 can anyone provide some pointers at what I should check first.

 

Thanks for joining, Rcorrea! Glad to have you as a part of our community

 

The most common cause of PO455 is a loose or bad gas cap. Check that first, it is the easiest.
