Well i think my o2 sensor came off or something. I was driving down the road and heard something scraping on the ground, i pulled over, looked under the car and saw that one of my 02 sensor's was dragging on the ground. What should i do?

I would get a new sensor and check the condition of the threads in the exhaust pipe. If the engine light is on, I would run it through a computer.

Thanks, the SES light has been on and off. The light went off when the 02 sensor came off...
