Can someone describe to me how the air flow meter works? I'm guessing that the little sensor hanging down just after the main intake is a temp sensor. Does the flap actuate some kind of potentiometer or something to indicate it's position (and hence the volume of air flow)?

thanks!

A good description you find in the Portal under EFI troubleshooting.

Doh, thanks. Guess I need to explore this site a bit more...
