This morning my Check Engine light came on. The car is still acting as normal. Nothing strange, no unusual noises. Fault code is P0496. I did buy the car 1 week ago and never put fuel in it cause I bought it with full tank. Yesterday I checked on the gas cap cause soon I`ll have to stop at the gas station and I think I might tight it way too much or not enough but I`m just guessing.
