  • Visitor,

    I had the check engine light on in my car, so I took it in to get a diagnostic. The mechanic explained that the car is designed to recycle gas vapors, and if some of those vapors escape through the gas cap, then the car detects that as a leak, and the check engine light goes on. He put a new gas cap on the car and the light's been gone since.

    Threw a vacuum leak code. Bought a new OEM gas cap. Code no longer appears. These cars are hard to kill...check your oil!
