Here's a picture of the culprit:



Can anyone name it? Its on the left hand side of the throttle body and seems to stem off next to the thermostat.

Thanks in advance!

 

that hose is for your FIAC valve (fuel idle air control)..
its the breather end of the vavle, the other end of the vavle should hook up to the middle top of the intake manifold closest the head... whats the problem with the hose? i think the one you have high lighted should hook up to the air intake pipe

 

if your putting an intake or turbo or something like that and you cant figure out where to hook up that hose you can just take it off a put a breather filter on it, my valve broke and honda wanted i think 270 dollars for a new one.....

i just stuck a bolt in the hose and clamped it shut - ha ha, it runs fine and has been like that for about 3 years now...
