Low Idle, Stalls out when coming to a stop
So yesterday I put a z6 intake manifold on my d15b2. Before I had a hunting idle. Now after we put it on it idles really low. I have a 1993 Civic dx so it doesnt come with a rpm gauge so I cant tell you the rpm's but i can tell that it is low. But sometimes when I come to a stop itll just cut off. I dont think there are any vacuum leaks. we used the same valves from the b2 manifold. so its not that. There is coolant in it. I really dont know what to look for here. Has this happened to any one else.

No its not a starting problem. It starts up fine. It just cuts off when I put it in neutral sometimes. And it idles low as crap

Did you mean d15b7? Because that's what's stock in a 93 dx not a b2. If the motor is d15b2 I hope you converted the manifold from dpfi to mpfi

set the idle according to the FSM. First I would ensure you have no vacuum leaks and you set the throttle cable tension according to the FSM as well.

A vacuum leak would not cause a low idle problem. You need an external tachometer to adjust the idle speed, as per Hero's diagrams.
