idle problem on 1.8t

[sam_1.8t]

right today I thought lets check my vacuum anyway the little vac pipe on the inlet was split and the long one that goes from the inlet to the dv wasn't even connected at the dv end so replaced both of them with new hose I then took the bottom hose off the intercooler passenger side and about 100ml of oil pee'd out.

anyway idle is abit funny still it idles lovely then you blip the throttle and then it hunts and you hear a click then idles perfect again
