it's Eg but with d15b2 DPFI

anyone know what is this hose for?
i have some idle and running rich problems and i think this hose is clogged

but don't know is it vaccum hose or some fluid hose... i don't want to mess up my brakes or cluch pedal

 

Vacuum hose for the brake booster.

 

sooo,can this mess up my idle or any other problems with the engine ?

or just mess up my brakes if it's clogged ?

 

It could mess up your idle if your booster is leaking (clogged would make a difference in brake operation).
EASY test to figure that out.

Disconnect the one way valve found in your fist picture and plug the end of the hose that is going to the engine.
Start the engine and see if the idle issue is fixed.

 

tnx dude

 

If your brake booster hose isn't hooked up you'll have a pretty huuuge vacuum leak.

 

god dammit this honda vaccum

hose is good and is funcionaling properly

still can't figure it out why my idle drops about 400-500rpm when i'm pressing brake or when putting to neutral while driving

on lpg car works ok,but on petrol is like ****...

 

Brake booster is bad. Replace
