Ok so i have a 92 civic hatch which has a 94 integra ls motor. The stock ls manifold has a black sensor behind it (not sure of the name/has a hose and sensor plug on it)which is opposite the side of the cold air intake at the end.I recently took it off so all thats left is what seems to be a metal tip for i think a vacuum hose. At this moment nothing is on their it just sucks in air. Do i need to custom make a hose or will keeping it like this be ok. Any help will be great.

 

just try it....if it blows up start over....lololol

 

That sounds like the EVAP purge solenoid (two wire sensor with a round plug) which is for emissions. You can leave it unplugged and there will be no consequences or check engine lights. Your car actually has that sensor also except it is mounted on the firewall by the stock map sensor, look for the two wire plug that is not for the map. There should be one power wire and a signal wire.

If you don't know how to differentiate the wires then just leave it unplugged.

 

So your saying the two wire plug for this is already plugged in on my firewall or should be on my firewall and all i have to do is unplug it and replug it onto the manifold?

 

no you would need to rewire it because the plug shape is different. Just leave it alone and cap the vacuum connection from the intake manifold.
