Car has been idiling erractically lately so I cleaned out Idle control valve ,but problem still exists. Now today I notice a black hose has split...but I haven't a clue what this hose does
and if it is linked to my problem.
The location of this hose is behind the air intake manifold. The pipe come from engine block and links into a T junction connector which has two pipes coming off of this,one pipe goes back into engine ,the other pipe goes into a cream coloured plug that is embedded in engine. Now I have a MK1 focus 1.6v year 99 Zetec E engine , any help identifying this pipe and what it does is much apprecieated.
I took a no. of this split pipe if it helps Ford 96 MF-6C342-CBC72GA..

Sounds like an engine breather hose .If it is split ,it will be drawing air and causing your erratic idling . Replace hose and see how you get on .
