the warning lights come on when I am driving. the next day only the triangle and the engine icon are on. the next day all lights are off. a few days later this happens again.
Some codes are detected only intermittently, and clear themselves after two driving cycles. One of the most commonly reported problems that causes scary warning lights is simply that the gas cap isn't closed properly. Open the gas cap door, open the gas cap, then close it firmly, making sure it ratchets.
