The engine has a fuel pressure regulator that looks at the intake pressure and adjusts fuel rail pressure so that the injectors always "see" the same pressure difference. This ensures the flow of fuel is tuely proportional to the electric pulse duration.
The AFM is bolted to the air box. First you need to get the air box out. Next there is a hose clamp that attaches the AFM to the throttle body.

Alright, I'll check this out.
Is it possible that the WOT switch is being thrown, but not getting to the DME? Is there a way to check this too?
