Ok, so I got a Skunk2 intake manifold for my b18c1 in my hatch.
When I was removing the manifold, I didn't really pay too much attention to where everything plugged up and now I'm lost. The gsr manifold is so damn different...

So I have no clue where the vacuum lines go. I put the one from the fpr into the small nipple in the back of the manifold. I plugged up the small one in the front with the nipple that came with it...What connects to the big one in the middle of the manifold? Do I run a hose to my PCV?? I tried this and the car idled at like 75rpm, almost stalling out. I ran the throttle body coolant line into the small coolant outlet on the side of the manifold..and I plugged up that metal one that comes from the side of the block with some silicon tubing and a bolt..The gsr manifold didn't have that small outlet, that's why I moved the coolant there.

Im throwing codes 21, 14, and 10

I know there is a green plug that plugged into the back of the block, and the grey plug i have plugged into the IAT sensor. There are still 2 more plugs that aren't plugged into anything. One of them I figure is for OBDII because i have an obd2 harness. and the other is for the butterflies from the gsr manifold.am i missing something..

Code 21 is VTEC spool solenoid valve circuit.
Code 14 is Idle control system malfunction, bad fast idle thermo valve, throttle body.
Code10 is Intake air temperature sensor.

Right now the big outlet on the top manifold is open so I have a huge vacuum leak. If I plug it up, the idle drops to almost 0. With it open, the car is atleast driveable, idling b/w 1500-1600 going up and down really fast. Idle gets smoother when I turn my lights, a/c fans, radio on...I guess the more load, the better the idle..

What do I do, anyone have the directions for the Skunk2 intake manifold install? I bought it used so i dont know what's up.

Also im using the stock civic cable with stock gsr throttlebody. I know i need to switch to a itr cable, pulley, and cable stay.

Help!?!? I need my VTEC!!!

 

hmm..

-the vacuum line you connect to the FPR should go to the nipple closest to the FPR not the back one. the back one should be plugged up.
-the big black plastic "bottle" should be removed if you have a GSR
-the middle valve or the "bigone in the middle" connects to your MAP sensor.

if you can take pics it would help, cause the metal one on the side of the block doesn't really help

 

The big one in the middle cannot connect to my mass air sensor b/c the mass air sensor isn't even on the intake manifold, it's on the throttle body...I'm talking about the big barb coming out of the front of the intake manifold. I found out it's supposed to connect to the PCV...

So the big one in the front connects to the PVC, the small one in the front connects to the FPR, the big one in the back connects to the brake booster, and the little one in the back is plugged. With this setup the car idles at like 75rpm. If I unplug the small back one it accelerates to about 750 which is perfect. It doesn't cold idle though because of the 3 codes it's still throwing. I guess the vacuum hoses are figured out, i just need to figure out the plugs now.

The green one goes into the back of the block, then they're are two grey round ones, one goes to the AIT sensor, but i dont know which one, and only one actually reaches the sensor. There's another square plug but that one was for the dual runner system..

 

ok i just looked my install.
sorrry i didn't mean the one on your throttle body. its the black and blue piece that sat on top of your stock gsr manifodl (IACV?). and your add another hose to the sensor to connect to your PCV (you were right) and another hose goes to your fuel filter under your battery.

the hose under your TB connect to the back of the block like you said. the coolant hose must be connected to a T-bracket and then extended to the front of the block.

the square plug that goes to the dual runner is left open.

 

have you reset your ECU?

 

yeah I reset it like 5 times. I dont have the sensor that sat on top of the gsr intake manifold b/c I was obdI and I had an obd2 harness. My mech needed the sensor so he took it and blocked off the hose to it with a bolt. I'm gonna run a vacuum line from the fuel evap canister to the currently open nipple, and hopefully everything will be dandy...

But then I will still have all 3 codes... Would there be any reason for me to have to extend any plugs? anyone else have any insights?

 

EVAP! thats what it was..sorry. im tired today.
what're you going to do with the PCV valve? don't leave it open. try to get a Tbracket and connect the PCV hose, fuel canister and theopen niplpe together. or even better, get the sensor back and see what happens when you connect it all back together. im not sure what sensors i have or what your missing cause im not too familar with the diff. ODB sensors.

the only reason i can think of the codes going off is the missing EVAP missing but you have OBD1. make sure all your hoses and sensors are in nice and tight without any kinks. i only threw a code 90 when i installed the manifold, but i fixed all that. good luck

 

The PCV is going to the big nipple in the front of the manifold.
The Brake booster is going to the big nipple in the back of the manifold
The FPR is going to the little nipple in the front of the manifold.
The Fuel Evap canister is going to the little nipple on the back of the manifold.

Grey plug in the IAT, green plug in the back of the block. Still have another round grey plug which i think might be the IAT plug and it just doesn't reach, and a square plug which is for the dual runner system and im leaving open..

Still throwing codes 21, 10, 14..

HELP!!!!!!!!!!

 

ok grey plug that connects to the top of the manifold with screws is in correct?
ok there should be anoher grey plug which your talking about that connects to the EVAP(blue and black plastic sensor) which you don't have.

when you say reach...reach to what?

 

Reach to the IAT. Because they're are two identical round grey plugs. One reaches the IAT, one doesn't. So I'm thinking that since I'm throwing a code for the IAT, that I have the wrong one plugged in. And since the other one doesn't reach, I'd have to somehow extend the plug so that it reaches the manifold.

 

Someone please help...still got 10,14,21..

TTT!!!

I'm gonna die if I dont get my VTEC back..

 

what year is your car?? more info pls so you got obd1 w/obd2 harness??

 

My car is a 95DX, the motor is a 96GSR with a 00GSR harness..ECU is a 95P72.
TTT.

 

Ok, i got rid of code 14 which was the idle control valve code, all I got is the AIT code, and I found out the reason i have a code 21 is because the VTEC pin fell out of the ECU plug..thing is that now I have no clue which hole it goes in?? It's in the middle plug I think, but there are like 4-5 open holes...anyone know?

 

Alright, I found the VTEC plug it's a4...now i have VTEC!!

Car dips but I still have code 10 AIT code.
