My Dodge Avenger's gas cap keeps popping off and the engine malformation light keeps coming on.

Answers from the Automotive Experts

Amy Mattinat, Owner and Author at Auto Craftsmen Ltd Hi Cindy, I would recommend replacing the gas cap. Click it tight at least 3 times and eventually the check engine light should go off - as long as the only problem was the gas cap not being tight. All My Best, Amy
