The AAR is not a smog component.

I would remove all of the smog equipment first and see where you are. THEN remove the auxilliary air equipment if you wish. It is all easily reversible, you have nothing to lose.

The AAR was added to the CIS in '78. Pre '78 911s used a hand throttle to keep the engine idle elevated during warm up. So, to me, this is a useless device. I just push the gas for 10 seconds or so until the engine will idle well on its own.
