I have 2000 3.2 TL with 79823 miles which I took for State Inspection. After waiting for about an hour in line the car hesitated when I attempted to start the car to move forward inline. Was able to start car and put car through the inspection process. I got notice that the car did not pass Emmission test because the Check Engine Light had come on with a code of P0171 (System too Lean (Bank 1). The TCS light also had come on. None of these lights were on before the inspection process took place. I drove the car home and the TCS light stayed on. I turned the car off and the TCS light stayed off, but the engine light stay on.
Any help with suggestion on the cause and remedy would be greatly appreciated.

Thank you
