Well, of course all of this is being filtered through Mom and me. Her exacts words were "it is the secondary air pump motor (it is losing its vacuum hence the whistle until it runs out of air)". I translated that vacuum pump (since I knew my friend's old Rabbit had one of those) and confusion ensued. Sorry.
I doubt that it has an air injection pump for emissions, but who knows, since it was originally a CA car, it might have. At any rate, Mom's happy that the pump has been replaced and the whistle/whine is gone. I'm happy that Miata's are made by Japanese engineers, so it's all good. :-) Cheers, Mark On Wed, Jul 30, 2008 at 2:57 PM, Bill Cardell <[EMAIL PROTECTED]> wrote: > I don't know why, but the Germans do like to put vac pumps on to boost the > signal to the brake booster.
