I have a 2000 ford focus zetec with a dohc and I found a vacuum leak up by my injeactor hoses and I don't know what it was connected to cause it looks like something broke off it and I don't know what it was connected to so if u know what it was connected to let me know ok please cause it causes my car to idle rough

 

There should be a vacuum diagram on the underside of the hood. try tracing the lines and it may help you find what that particular hose gets connected to.

 

yeah I tried that but it much be long gone cause its a used vehicle and im try to get it up and running the right way

 

You might the Autozone website.
They require all the specs for your vehicle, which I don't have, but you can usually get a pix of the vacuum diagrams at no cost, give it a shot.

 

ok thanks
