new here and been reading up that it's normal for the Boxster to give off some smoke during startup. But the other day on the highway, I kind of got on the car pretty hard and when I looked back there was smoke continuously pouring out the exhaust. The engine light came on so I backed off cruising about 50. After awhile it went away. This has happened about 3x now ( whenever I accelerate hard or floor it ) Anyone know what this could be ? Is the car burning oil ? Thanks.
