Huh, interesting. Thanks for making that observation. In the Bosio thread pimpernell posted the following:
Quote:
I don't mean to beat a dead horse, but the shop manual for the 96 model reads as follows:
Idle speed to 2550 plus or minus 100rpms...both flaps should be closed.
From 2550 plus or minus 100rpms, to 3350 plus or minus 100rpms, intake resonance flap opens, and intake manifold resonance flap is closed.
Over 3350 plus or minus 100rpms, both intake resonance and intake manifold flaps are both open.

So it looks like this literature could be wrong.
