Getting CODE P0456 EVAP LEAK! Help!
Hey guys, search the forum and I came up with nothing.
I'm getting a P0456 code that says (evaporative emissions system leak detected) (very small leak). The initial observation was the gas cap so I replaced it with a brand new oem one and cleared the code. Drove for like 120 miles and one day on a cold start the code came back. Any ideas on what to check next? I have checked all the visible lines and couldn't detect a leak from any of them. Theres one that goes down in front of the air handle and I lose it so I might need to check that one to the source. Any help or suggestions would be greatly appreciated.

I'm not sure if this helps, but I had this same thing happen when I used bad gas. I replaced the cap and did the same, but after running the tank of gas low, I refilled at my normal gas station with 93... cleared the code and it went away.
