Exclamation Vacuum leak, no idea where!

I just replaced the distributor, cap, and rotor after having some issues with hesitation, misfire, and loss of power. I also recently replaced the MAP sensor and IAC valve and both connectors. Now there is a loud vacuum hiss and I cannot identify where it is coming from. All of the vacuum lines have been replaced with vacuum hose. So it's all new. One thing to mention is that I did melt a piece of the EAC solenoid when soldering some wires, but it only is a corner of the plastic housing.

I made a video to better illustrate the problem:

I would suggest back tracking and checking every connection you made with the new vac lines you replaced
