vac lines hooked up wrong

so i replaced my exhaust manifold, it all went really smooth. i was pretty sure i hooked the vac lines up right, so i fired it up when i got it put back together, when it fired it revved way up. i switched the vac lines around again, same thing. the throttle isnt stuck, but it acts like it is. i bled the fuel off the line, tried it again, and the same thing. i unhooked where the fuel pressure regulator hooks into the fuel rail, still no change. idk if this is a vac line problem, injectors, or something else. i got a vac line diagram on autozone and hooked it up like that. its still the same thing. idk what else it could be. any help would be great.
