This week my car started making a ticking sound the more I accelerated the faster it went it was quite loud.. Today it was doing this And all of a sudden the car stopped and quit. I was on traffic turned the key it started and the started shaking and turned off again along with my sterring wheel locking up... Eventually I got it to stay on long enough and accellerated and shook my way to the side of the road.... What is wrong?? Plz help
