St215 (caldina Gt-t) 3sgte into a St185 Celcia, Vacuum Lines help

[90CelicaGt4]

Hi Everyone,

New to this forum, Hoping someone can help with this. So I have put a St215 3sgte into a St185 celica Gt4 and i have these two vacuum lines open. Does anyone know what i need to do?

The engine currently will run for about 1 minute and then it will slowly fade off and stall (revs will drop). I'm thinking it maybe these lines open?

By the way these ends are just under the throtle body
Please help

the fat diameter one is your idle air control feed tube to your iacv under the throttle body. the little one is vacumm line into your blow off valve. this one should come directly out of the side of the intake manifold. right behind the throttle body.
