I am having idle issues and I believe I found the causing leaks, but not sure where these lead
to. Any help and pictures would be nice. Thanks in advance!





I also have this open. When I have the car started and cover this it stalls out. But the vacuum line from the other hoses arentt long enough to reach this.

It looks like the map sensor vaccum houses

U should have some thing that looks like this all three go there

What year is ur teg and do u have the stock motor

I think IM missing something. I have a LS Vtec..
After looking at a vacuum line diagram seems like missing the evap purse control canister?

But ivee seen other LS v setups without that evap

You need to plug up at least the one in the manifold. It's making your motor run lean, and your map sensor is not reading that amount of air entering the motor.

Those other two from the first picture are from the charcoal canister. The smaller one goes to the purge solenoid and the bigger one goes to the top of the throttle body where there is a black nipple already on it.

Yeah IM trying to figure out the one on the manifold goes to. When my car is running I hear it sucking a lot of air. I cap it off it shuts right off so it has to connect to something.

Sorry my mistake one of them to got the throttle body the other two should go to the map

The two coming off the charcoal canister don't need to be hooked up if you're obd1.

The small nipple coming off the back of the manifold needs to be blocked off,
it's sucking air all the time bypassing the throttle body.

Depending on what kind of ecu/tune you have, your car may run funny if it's a stock gsr.
Also may want to check your IACV on the back, you'll have idle issues that seems like a vacuum leak if it's dirty.

??? The map is directly bolted to the throttle body and it does not need vacuum hoses.

It is connected to the purge solenoid. You need a short hose from manifold to the bottom of the purge, and on top of the purge goes the long small diameter hose that you showed in the second pic.

U stand correct ones more i would jz do what cleanlikejdm Thats seems like the best option

When Its blocked off... the car starts but it dies right away. When its left open it stays running but sputters.

that looks like a b16 manifold. the nipple on the back is for cruise control on civics. you need to cap it off.
