Loud noises When driving my car down the highway i attempted to reach the speed limit which was 55. Once i hit 45 a loud cranking noise began to occur, sounded like it was coming from the engine. Then i began to smell burnt rubber. I began to drive back home and upon reaching 45 mph my car felt like it was pulling back and making a loud noise and then shut off. I tried turning it back on but it just made a loud sound and didnt turn on. The check engine light came on but then turned off. Once i got my car to start again it didnt go passed 5 mph and there was still a loud cranking coming from the inside and it sounded like something underneath the car was rattling. It said check gauges also. when i reached anywhere passed 10 mph it completely shut off and i'd turn it back on and proceed, but it still had that awfully loud noise. It turned off about 5 times before i finally made it home. But it still keeps rumbling and now wont even turn on. what could be wrong?
