    sometimes after fueling or just by turning on the car the check engine light would come on and it would say check gas cap so every time i would fuel i would tighten the gas cap extra hard and i would push and tighten and i never saw the check gas cap message ever again.

    I have had to replace my gascap several times over the last few years. It gets frustrating and expensive.
