If it was going OK, then chances are it still wants to.
Just a matter of getting control to it.
And it is all too easy to knock one of these pipes without noticing, or pull on one as you reach around the back of the manifold, so that the connection is poor and you have a vacuum leak (or, more accurately, an air leak into the vacuum system)

But don't forget that the pressure sensor downstream of the intercooler will have been disturbed (including wiring) when the intercooler was changed, so there may be a latent failure from that effort.
