How do I find small vacuum leak P0442 2006 chevy colrado 2.8L

Question

My Chevrolet Colorado is showing code P0442 evaporative system small vacuum leak- How do I identify the leak - what do I look for in the Engine - I only see two Vacuum lines behind Air intake Box ?

Answer 1

This leak is for the evap emissions. I would start by checking the seal on the gas cap and check the surface of the fill tube. If anything looks like it's not sealing clean it or replace it. If that doesn't work then you will likely need to have a smoke test done to find the leak
