Hey people,
just goin over my engine today and discovered a split hose, that connects from the throttle body to the inlet manifold. My car has been idling rough for a while and im wondering could this be the problem?

Quite possibly. Take the hose off and give it a good wrapping of electrical or gaffa tape covering every part of the split. Replace and see of that helps.

The proper solution would be to replace the damaged hose. Vacuum hose is like $3 per metre from super cheap in all different sizes so no excuses for not doing the job properly. Recent did the same on mine. The hose from the throttle body to the boost bypass valve was split. Slightly improved fuel economy and smoother idle.

give the TB a good clean also, a can of carb cleaner works well but it's better to remove the TB to do that. make sure the passages for the IAC are clean
