    • Confirm P0171-System too lean bank 1 (or single bank) Scan data for fuel trims shows slight rich condition at idle and very lean condition under load, where the more load is applied the leaner the system gets. Idle trims are -5%, and loaded trims are over +35%. Idle MAF readings are a bit high, and high RPM readings are low. Remove and inspect MAF senor and found sensing wires covered in dust buildup. Clean MAF sensor, install and recheck fuel trims. Trims now correcting back to zero +/-3%, and throttle response is improved. Clear codes and road test, system normal.
