hi Eric,

I don't want to pileup on your topic but since we are talking about *"not
running right"*

There's a gasket behind the throttle body... when it fails the engine has
the *"not running right"* symptom too, quite similar to the vanagon
syndrome... It's very easy to replace.
That bad gasket allows more air in and makes the fuel/air ratio wrong, the
AFM itself can't not correct it.
