So, yup IAC is like a huge vacuum leak! I put it back online on my manifold with the MAP line and all 6 ITB lines and I got 94 plus kpas.

Back to the drawing board, I guess.

Open to suggestions, but really, really want this thing to start up like it was a Toyota in all temps and conditions.

Would taping another port into each ITB do the trick- one set doing IAC and the other getting a MAP single?

Open to all suggestions not involving hand throttle or holding the pedal slightly until it holds idle- sorry guys!
