Po442 code Help please!

[mickey]

I spend a month to figure out where is the problem. I know the exact code for but i don't know how to find where the exact parts i need to fix so i can get rid of check engine light before I go to emission. im kind of stress because i already replace gas cap but still check engine on so it not gas cap. i check lose hose for evaporation system but i think i found it because i see a wire is unplug but still check engine light back on. i have no idea what to do.

Find a shop that has a smoke machine, they run smoke through your evap system and find the leak.

Did you reset the codes after you fixed this?
