(no it's not my gas cap I have replaced this)  Guys at local auto part store told me to take it to the dealership (YIKES all I heard was a cash register ringing out)

The trouble code P0442 is a small leak in the EVAP system. The EVAP system pulls gasoline fumes from the gas tank into the engine to be burned instead of being released into the air. You need a smoke test to find this leak. The leak can be SO small that it can't be seen with the naked eye. The shop will force (harmless) smoke into the system and look at the EVAP system lines. When they see the smoke coming out they'll be able to find and repair the leak. HTH. -Jim
