That relief line will have about 2 psi at 3800-4000 RPM between the air pump muffler and the ACV.

You only need about 1.8 psi to fully open the S4 aux valves

Here, this is an picture.

I colored the line blue so that it is easy to see in the picture.

We did what you said, found out the ports are definitely stuck, although we managed to get them to open and now they are stuck open halfway and won't move anymore.

yah so we ran the line into the acv relief hose thing, but then we noticed the aux ports were still not opening, we tried to manually open them and could only get it about half way and then wouldnt go any further... as well we then couldnt get them to go back closed

Icemark

Yeah, they have to be working normal/correctly to start with.

Time to order some intake gaskets and fix them

ddub

yippie!


in the process of all this i also was trying to set my TPS and either we were doing it wrong (which i doubt cuz we tried various ways multiple times), maynard5000's meter was messed up/broken, or my TPS is dying and i gotta order a new one of those too.....

i cant wait till my fc is finally working properly, seems like every time i fix something, something else comes up or is discovered
