engine starts then stalls

just installed a new engine. if i keep it floored, it will start. then i took a vacuum hose off the intake. it will start and stay at about 1K and idle up and down. when i plug that hole, it will die. what do i need to replace. its a 93 with borla headers, 2001 intake, and 19lb ford injectors. thanks in advance.

btt.

What does the vaccumn hose go to?

nothing, it was an extra hole so i had it plugged.
