A new 300zx owner, eh? Well, in behalf of the Z nation, welcome to hell. We hope you enjoy all the troubles that the mighty Fairlady will bring upon you. Hah, but to answer your question. I would call Z1 and explain your situation and see what they recommend. Like always, I'm pretty sure it's just some hose(inside joke, you probably won't understand it) that the shop forgot to connect or something along those lines.
