I got a check engine light on my dads 99 Ford Windstar which is fuel tank pressure. So I check the gas cap and noticed that it doesn't click. I don't drive this van much so I never really noticed if the gas cap clicks or not. All the others cars I've driven the gas caps click. Is it a Ford thing that the gas caps don't click, it feels like its just a 1/4 turn to tighten. Thanks.
