Default Ok I really need some help with these Evap leaks...
I'm totally clueless. My car keeps reading the codes for a small evap leak and a large evap leak. I tested the gas cap and it's fine. I'm really just not sure where to go from here. I'm sick of looking at this CEL, anyone with any ideas?

How do you test those check valves? Air should flow one way only?
