I don't know much about cars so I am trying to see if someone could help me. This happened about two weeks ago, I was driving and my car just started shaking all of a sudden and then the check engine came on. Since then whenever my car shakes the check engine light flashes, but when it doesn't shake the check engine light is just on, but not flashing. Sometimes the light turns off but usually turns back on the next time i turn my car on.

Thanks in advance
