I just recently put the engine in this vehicle, and I was doing it in parts which took a little time, so I have a brain block on where the vacuum line on the IACV connects to. There are three ports on the IACV, two are coolant lines which I have connected but I can't remember where the vacuum goes. I have a photo of the IACV and have the vacuum highlighted in red.

That vacuum line goes to a small port on the intake manifold near the #4 cylinder. Here is a diagram to show you. How did you make out with the crankshaft sensor? Check out the images (below). Let us know if you need anything else.

Another problem I'm having. The car idles fine but whenever the accelerator is pressed the engine stalls out and dies. I changed the fuel pump and injectors, but I don't have the right tool to check fuel pressure.
