So i just got done replacing the intake on my 98 Ram 318 with a cleaned up salvage part and I have a coolant leak (which Im pretty sure i know what the issue is there) but my big problem is a vacuum issue. On either side of the intake are the vacuum ports, on the driver side there are two ports. One that connects to the brake booster and the other one was plugged on my old intake. So I went to plug it one the new intake and the truck dies right out. Start it again and the same thing happens. My dad has the same truck and the same port is plugged up on his and it runs fine. ANY IDEAS ARE WELCOMED!!!

 

If you give it pedal does it still stall? If not IAC valve isn't functioning.
