If you don't know where the air leak is, you will have to do one of two things. Take a length of hose, hold one end up to your ear, and trace the other end around the engine bay, mainly following hoses or any other part that allows air to travel. The other option is to do a smoke leak test through the air intake and see if any comes out as it travels to the engine.

 

I have mine being work on right now. The throttle body is defective and needed a replacement said mini service center.
