My 1996 900S makes a lot of SAI noise for the first 2 minutes. The vac hose from the firewall to the ... something? (see picture link below)... is rotten and i replaced it. While I was at it i popped this valve off (i think it's a valve. what is it?) i blew into both sides and nothing came out the other side. is it broken or normal. It plugs between that hose and something that looks like a diaphram (what is that thing? no picture).
silly me, i forgot to mark which way it went back too. i think it was black side down -- ie down into the diaphragm type thing and red side up to that vac hose to the firewall.
funny thing though when i had the vac hose off and started the car -- SILENCE at last from the SAI. So currently I plugged the nipple on the firewall and am not connecting my new vac hose there and am starting up silently for once.
