I took my truck back to dealer for a po 449 evap system circuit malfunction. They replaced the sensor and I guess its the vent hose but they ran it all the way up on top of my trans. no light for like a week. Now im getting a po 442 which is a small evap leak. Ive checked all clamps and my gas cap is tight and in good shape. Is there anything else I can check before I take it back? Its still under warrenty but its a pain to take it back. any help would be appreciated thanks.

Have a custom tune? If so, have the EVAP system disabled. Its a PITA.
