ive just finishing putting a silvertop in my ae92. it runs fine however i just noticed 3 hoses that arnt conected. they all come out near the intake manifold on the passengers side. two are joined togeather with some rubber halfway down and one of these sucks air in and the other doesnt seem to do anything. i noticed that if i blocked the vacuum pipe the idle dropped and if i touched the ends togeather the idle raised quite a bit.
the third hose has a very small diameter and doesnt seem to affect anything.
what are these hoses for and any advice on what i should do with them would be awesome.
cheers
