  1. Exhaust Gas Smell /Vent Solenoid

    Problems and Service
    I have a 2006 Cobalt LS Auto store said I had a vent solenoid bad. I changed the gas cap cause it was worn out. Now it has gas fumes coming from the exhaust. I wanted to try putting the old gas cap back on but I've already tossed it. Thanks for any help you can give. What I've done...
