P 1 10 1 The performance failure of the intake airflow system may be the air leakage of the intake system or the damage of the air flow meter. It is necessary to check whether the pipeline between the air flow meter and the throttle valve leaks or not and judge whether the air flow meter is damaged. You can unplug the air flow meter.
