While I was driving on the street my car completely powered down, I was so scared, because there was moving traffic behind me. I tried stepping on the brakes and then hitting the gas again but the car would not move. I had to quickly put my parking lights on and pray that no one would hit me. Then I turned the car off and on a couple of times and it started moving, only to power down two blocks later. I was able to pull over to the side this time and I waited a while and then turned the car back on. This time the service engine light came on. I took my car to auto zone and codes came up for the speed sensor and throttle sensor. This was so scary and hazardous, thank god I got off the highway beforehand because there was too much traffic!.
