probably an incredibly stupid question but where the hell is the maf sensor at? i checked my haynes manual and i can't find it. hopefully someone can give me a real quick answer..

 

Under the airbox.

 

MAF = Mass Air Flow

Where is the most mass of air flow coming from?

 

It is called an Air Flow Meter (AFM), which is a specific type of mass airflow meter. It is larger mechanical version of the newer and smaller hot-wire type of mass airflow meters commonly called MAF sensors. As mentioned by Hecubus84, it is located on the downstream side of the air box. Do NOT monkey with the AFM if you don't know what you are doing, as it can cause permanent damage and the car will not run without it. See the FAQ section of this forum for links to online manuals that will show you where it is located and how to test it without ruining it.
