Why is my engine smoking and shaking

I pulled out to turn from a red light and I kind of gave it some gas and the check engine light came on. Then, the car just started shaking, so I pulled over to a close gas station and sat a while with the car off. Then I tried to start, but it wouldn't, so I tried again, and it started but only stayed on for a few seconds and started smoking and turned back off. Last week, I went to turn it on and it shook very hard and started smoking again, and I just went to the car to try to turn it on and the car is dead.
