I'm a little confused as to which port you are talking about - there is only one air supply port to the ISC if I recall correctly, and it is required, without it you cannot idle.

I have mine inbetween my throttlebody and gm maf and have had no problems. I am also running the maft in blowthru. Some say just put a filter on the isc valve but I havent tried that yet.

The way cnewingham has done it is about the only way I can see to do it right. Putting a filter on it will suck in unmetered air, which will screw up your idle. Hooking it up to the pcv port on the TB will not work either as that port opens up behind the TB, so in essence it will suck in air that's already in the plenum to put back in the plenum...redundant. THough in reality it will just be a static loop and not suck anything at all.

You could cap it too if you want. You just won't have high cold idle, idle up for a/c and things like that. Just use an 87-88 TB with the idle adjustment screw and it will work fine.

Yes, but if you use your maft in blow through (or even suck-through for that matter), you need to get your isc valve air source from BEHIND the maf sensor, and in front of your TB, so the 3000 pipe is the easiest place.
