Customer Question

I have a 2009 bmw x5 4.8 . I was driving home and the check engine light came on . The engine started shaking. When I took it to the mechanic . He said he needed to change the spark plug, and the coil. He put it in the machine again. It came back again as a cylinder #8 misfire. He changed the injector. And now the car runs the same and still come back the same. Do you know what might be going on with my car?
