I have a 1998 Lexus ES300. The code showing up is P0171 – System too Lean (Bank 1). What does it mean?
have the same problem?

Lean fuel condition could be caused by one of the following below:
1. Vacuum leaks
2. EGR and PCV valve.
3. Low fuel pressure.
4. Dirty fuel injectors.
5. Mass Air Flow Sensor.
6. Oxygen Sensor.
