What are you trying to ask?

The AFM is under the factory air filter box. It connects with the black intake tube going to the top of the motor. The connector is on the side of the afm and must be disconnected to take out the afm. Disconnect the battery to reset the computer.

Are you getting information from friends? If so, don't.

There is no throttle body under the airbox. The AFM connects to the airbox directly which then has a tube connected to it which, on a n/a, goes up to a plastic elbow which then connects to the throttle body which, by the way is on the top of the all 13B rotary engines. The throttle body then connects to the dynamic chamber to the upper intake manifold, then the lower intake manifold, then to the engine which, which in theory will help the engine go............VROOOOMMMM. OR in special cases, BRAP BRAP BRAP!

On a turbo engine, the AFM is connected to the air box with a tube connecting the afm to the turbo which then connnects to the TMIC which then connects to the TB and so on....

You must have a turbo im guessing.

Now tell me why nothing goes to the top of the motor?

To help you further understand the airflow path. There is an image like this for a turbo engine as well, just put a turbo and intercooler betweem the AFM and TB an you will be all set for the image.


What is the problem?
