Default Evap Leak Codes?
At 68,183 miles, I got a P0441(Improper Purge Flow Evap) code. I reset it and no CEL until 72,144 miles(P0455 Large Evap Leak). Can anybody fathom a guess on where to start looking?

Self test with the proper diagnostic tool, and then smoke test to see where the leak is.

Cheers
