When in drive and stopped at a traffic light, the car almost stalls out. On two occasions the car completely stalled and did not start the first time. I took it into the dealership where I bought the car and they tried to sell me the 30,000 miles service pack. I refused to pay over 300 hundred dollars for that. They said they would check the car again and called me back to let me know that it looked like my fuel injectors were a little clogged. So I had the fuel injection cleaning done. Well the car still runs the same, almost stalling and it seems worse. I called the dealship and told them and they just gave mean answer,"bring it in". So my problem still is not resolved. I have also heard that there may be a recall on the catalyic converter.
