2000 MAXIMA SE STALLING
 

I have a Maual 2000 Nissan Maxima SE that stalls when I am slowing down. I can also hear a whistling sound from the engine...... I do know that there is a connector that has the airflow meter and another censor mounted on it is not connected to the airbox. I dont know if thats the reason the car is stalling. It isnt the airbox itself, its a piece that on one side connects to the airbox and the other touched the front tip of the car! Can anyone help?
