Check engine light comes on/off intermittently. Have installed 3 new gas caps, which helps for a week or so. It seems to stay off when the tank is full, but comes back on at 3/4 of a tank. Using high grade fuel. No resolution found.
Car drives great , but went to my bank. When I started it up . Check engine light came on . And won't go off
