What is your question?

The check engine light is on before I start the car but turns off once car is started. The car stalled and lost all power when I tried to excellerate to get onto freeway entrance. When I tried to restart the car the engine won't stay on and car shuts off as if it has lost power. Also, it almost sounds like a wissle or hissing sound sometimes when I drive at faster speeds. Windows rolled up I can't hear it, window slightly down I can faintly here it at times.All the lights and electrical things work. Car just stalled and cut off. Car will turn over, idle for seconds, ( I can give it gas and raise rpms but in the end cuts off) and then cut off

What makes this problem better or worse?

Car won’t drive so can’t get worse, only better

How long has your 2013 Jaguar XF had this problem?

Just bought car 2 days ago
