Where is the Vacuum line PLEASE!!!

[sparkone]

I got an 02 expy 5.4, where's the vacuum line located at? It will be appreciated.

I guess it depends which one you are looking for as they are all over the engine.

I'm looking for the one that gives the expy a rough idle. Anything will be appreciated.

Try search for rough idle. Or try this link. http://expeditionforum.com/showthread.php?t=4926. Hopefully will help you. It worked for me and 10,000 other Expy owners.

Thanks!! I think it needs to be replaced, no codes are coming up.

Well any vacuum line leak will cause high emissions and a rough idle. All or most of the vacuum lines connect to back side of the throttle body or somewhere on the intake manifold. A really easy way to find a vacuum leak is use a fog machine and pump it into the intake manifold and you will find you leak very quickly.
