New to the forum, so apologies if this is in the wrong spot. I just put a new long block in my 87 4runner, and used the original intake. It will fire up, and run on carb spray, but dies out quickly. I found a massive vacuum leak, but I have not been able to find how to fix it. It's a small port underneath the cold start injector and for some reason I haven't seen it on any diagrams. If anyone can help identify this it would be greatly appreciated. Thanks in advance!

The hose that goes to that port runs straight down and connects to the back of your idle air control valve (IAC) under the intake manifold
the part# for the hose should be 22234-35010. But please confirm the application before ordering/buying.

That makes so much sense, thank you. I'll try connecting it with a piece of hose and see if that works.
