REPAIR DETAILS

Earlier this week, my car would not start. After jumping the car battery, I kept the car running and even drove around and everything was fine for the rest of the day. The next day (yesterday), I started my car and put the car in reverse. Ater this the car's engine started shaking. I put the car in drive and the engine also started shaking. When I put the car in park, the shaking stops, but I can hear and feel the engine knocking.
