The airflow meter frequently fails but prior to replacing it I would want to plug in a scantool and look at the air flow values at idle cruise and while driving. Nissans set a code for knock sensors frequently but fix the airflow meter code first erase the codes drive the car and see if the knock sensor code returns. It could set a knock code if the airflow meter was giving problems.
