I have a 2007 chevy cobalt, it is starting hard and idling very rough. It is also smoking out of the tail pipe. It smells of unburned gas when it is running, when I can get it to turn over. My check engine light is also on, and when I am driving it is blinking. It also has lost power and acceloration.
