The photo shows a vac hose with a bung in it, which has stopped the rough idle, I need to find out if its mean't to have a hose fitted and if so where does it come from.

It will take someone 30 secs to look please? it's at back of engine below rear of throttle body, one small vac pipe and one big pipe.

Thanks
Dan

 

Sorry it took a while, cleaned my throttle body today so had a gander and took a photo as I'm not very knowledgable and can't see too muh in your piccy



If it is the circled one, it is a 90 degree angle one then has a smaller cable coming out of it. This then runs to the left side of the engine by the bulk head. Goes into a black plastic cylinder that's attached to the bulk head at the back of the engine.
