Hi does anyone know why this plug would be disconnected from each other. i was checking out under the hood this morning and fond this plug disconnected. the plug goes from the air box with black and yellow wire then changes to Blue and green and them seems to go to the MAF meter (the only odvious blue and green under the hood). i reconnected the plugs and there are no codes engine runs fine as it did before. if anyone has any clues and what exactly this does that would be great info. here are some pictures of the plug next too the air box.

 

I believe that is the plug that open the flap at the bottom of the airbox for additional airflow when engine is under load.

 

Thanks Casper that is great, don't know why it was disconnected all seems fine with the car.
