Remember in my introduction piece where I mentioned I'd be asking really noob questions from time to time? This is one of those times...
Apparently I really, really suck at reading diagrams in this shitty Chiltons and after some searching I'm still at a loss...

Could you guys please help me!
-93 Si
-Black box directly behind the battery (outlined in dotted blue)
-There is a vacuum hose coming out of it (highlighted in blue) below the two wire connection, that was just hanging there. After a quick search I didn't find where it should be attached.




-I assume this could be the reason I get idle surge occasionally a few minutes after start up, until it warms up fully? My first thought when I bought the car and found that issue of idle surge, was that it was the FITV, but if it was, wouldn't my car have immediate idle surge upon start-up, instead of a few minutes later?

 

It's actually, called an intake control solenoid. It controls intake air noise.

 

On my accord its hooked up to the throttle body. Clean out the fit. Then open it and screw it down

What's actually called the intake control solenoid? The black box I highlighted?




You're referring to the FITV? Correct? It's on the throttle body of Preludes then as well... what I'm aiming to figure out is, what is the black box that's located behind the battery, and what does the highlighted hose connect too.

 

And how do you quote multiple people? I'm sure I've seen posts quoting multiple people...

 

No im talking about the black hose coming of that black box with a connectoe. The hose goes to my throttle body. But thats on a accord. And for the fitv i dont remember where its located. If you know what the iacv is then follow the coolant lines should be connected to the same coolant lines. Find it open it and screw it down i believe clockwise.

 

 

doesnt that black box operate functions for the oem intake?? brain fart atm but ill try and find the thread ive seen it in.

 

Yeah, that box controls a flapper down in the intake box in the fenderwell. Since you have an aftermarket intake, follow the vacuum hose to the intake, and cap it off there, then pull that box out, and you can pull the intake box in the bumper as well, that is unless you want useless crap in your car.

 

Ahh yeah, now that I know what it's called there is plenty of info about it out there. I'm just a tard and couldn't figure out what it was. Thanks guys!

 

That's better Thanks guys!
