Hey, i'm kinda desperate for an answer on this, but on the H22A... on top of the plastic casing for all the injector wires, there is a black cylinder with a vacuum going into it and a hose going out of it into the intake mannifold. I was wondering if anybody could let me know what that is called and what the plug in it is and if it is necessary? thanks a lot!

Sounds like the idle air control valve. Yes, you need it.

 

where is it at on an '92 H23 ?

 

If this is a JDM H22A and not actually mounted to the manifold then that is not needed. It is for the bypass butterflies in the resonator. The USDM 'ludes have the control down near the battery.

You can take it off, just be sure to plug the vacuum lines.

 

pics would really help

 

Ok, the pic makes it more clear. I don't know what that is.

how much does that lil thing weight on USDM Ludes?

 

I was told its a fuel pressure riser...not needed.

 

thanks a lot for the link to the thread cottonwoodz... i now know everything about honda engines it did help me out a great deal tho. thanks again

 

actually its the evap purge valve, you don't need it unless you are trying to pass emissions.

Are you 100% sure on that?

Bull....I passed Emission with my CAI without it..hehe

So if its the purge valve, and you dont hook it up, you will have problems with the Evap system?

 

its is used by the jdm ecus to modify the vaccum going to the fpr, you don't need it, just go ahead and remove it and run the vac line from the fpr straight to the manifold nipple.

 

We got like 10 different answers on this now..

 

jeez... a million answers to what it is, but they all lead to the same good news--&gt; NOT NEEDED... so i'm good.

 

it is the evap purge valve, it isnt connected on my friends swap, no big deal

 

That black solenoid is the fuel pressure riser where in cold starts it blocks vacuum to the fuel press. regulator thus rising pressure and richens up the mixture for quicker warm ups and to get the system on closed loop quicker. same principle on cold start injectors used as is some late 80's and 90's early toyotas. this is not part of any Federal or California emission feature. the 49 state and California preludes use a fast idle valve which is located also in the intake manifold close to the IAC valve and a vacuum hose runs to the intake pipe near the throttle body on the other hand the JDM engines have this blocked off whit a plate. You can hook it up if you know the pin number of the ecu side, or just take if off and ignore it, but if you're trying to get your engine BAR approved(Ca, peeps) I would take it off and apply the related components that are required for the inspection. and no this not a purge solenoid and second. butterflys solenoid as this solenoids are located in totally different locations.

Im going to have to call bullSHI!T on that,,,No wait......DAMN it

 

Actually now that I think about it... I think you were the one, that told me it was for more fuel on cold starts..

 

didn't you have 1st. gen. integra with the H22, this was way back late 90's on the hybrid board. if you are do you still that ride..
