Best Answer

Did you put a factory cap or factory replacement back on or a new generic cap. Most older vehicles require a vented cap. Newer vehicles with emissions need a sealed cap, the tank is vented through the vapor system. If the car can draw air through the cap it thinks there is not one there!
