i need help...I am having problems with my RBC manifold

nyc06tsx · 08-13-2008, 08:54 PM

well this is the problem.. after installing my RBC manifold i got a EVAP code on my dash.. The problem is that there is two vacuum lines coming off the left side of the fuel rail, one is connected somewhere to the block under the intake manifold, and the second one WAS connected to the original intake manifold but the new RBC manifold doesnt have a place to connect that other line so because of that i am getting that code and the car is running at 1500 RPM when is in park...

can some one help me where to connect that other line.

Maybe you can find your answer in this article... it talks a little bit about the k24 intake manifold. http://www.hondata.com/tuning_k24a2_tsx_engine.html

I beleive you are going to need some type of tuning ability to make sure that RBC works right.

you try plugging the hose? or put it to a vacuum?

What's an EVAP code?

Did you install the RBC manifold yourself and is it a proper install? I knew several people w/ RBC installed but never have the problems you had.

I did had 1500rpm idling issue awhile ago, that's because I have swapped in a 06 IM/TB + bored it out to 71mm. The throttle body resting position (NOT the TB itself but rather the mechanical flip inside) was off, it's not been fixed.

It seems like you missed something in between.

One Vac. line is for the front engine mount, I forget what the other one is for but on the RBC manifold, I know for atleast one of the vac. lines, you have to tap a hole under the manifold in order to run it properly.

you need a hondata intake gasket

Have you fixed the problem yet?

Does our throttle body fits on RBC perfectly? Maybe it needs a throttle body adaptor for RBB TB to fit on RBC IM.

nyc06tsx · 08-20-2008, 03:00 PM

The TB fits perfect with no problem... and yes i still have the problem.. but is ok... i dont mind the high rev but just that stupid check emission light is on

Did you use a new Throttle Body gasket? Usually when you remove the throttle body from the intake manifold, the gasket gets damaged or will not reseal properly which causes a small vac. leak..
