P0171 System too lean bank 1

My car is now running rough when its cold and rarely tries to stall then too. The turbo isn't acting any different. The car has just under 130k on it, please tell me I can just replace sensor A and not my turbo...

The turbo is more then likely fine. It sounds like the sensor is not getting a good signal.
