Code PO442 came up what do I do.
First thing is to remove and re install the gas cap. Then clear the code and drive it, maybe that is your only problem. If the code returns then you will need to do fuel vapor evaporative test to find the leak. If the code does come back and you feel it is too much to check yourself try checking with a dealer that used to have Saturn it may still fall under an emissions warranty.
