Thank you bwojdyla and all the contributors for the great help.

I've experiencing idling problems on my 00 Zetec. The engine would stumble and die at idle or rev to 4000 rpms hang there for long duration.

I found the hole in the hose today and will fix it tomorrow. Just made a temporary seal with some silicone.

Once again, thank you to bwojdyla and the whole Fanatics forum for their photos and guidance.

Anyone know the trick to getting the clamp off of the back?

Thanks EDIT : GOT IT!!! Just pry the loop in the clamp with a very small flathead screwdriver.

This site is great!!

They are similar parts, except the XS4Z has insolation from the heat and the one end is shaped differently. Almost as if the 2000 Zetec has something to interefere with the XS4Z from working. See images:



The updated one fit right? I would think it would kink off easier

The service manager told me that I may not notice a big difference.

As I said before, I am going to look into the engine mounts when I get a chance.

I don't know... the car runs fine (no stall, no stumble, plenty of power), just has this vibration that I think is excessive. I may just have to chalk it up to an engine with 60,000 miles on it.

Thanks for everyone's responses here!
Yes, I am quoting myself! I just essentially solved my vibration issue with my engine. I finally got around to changing the Fuel Filter... at 89,000 miles (!! ). The car runs essentially 100% better. There is still some vibration, but I figure that is acceptable for approaching 100,000 miles.

So, for any others with the vibration issue, Check Your Fuel Filter!! Or, just change it. I think most of my vibration was the engine making up for a dirty filter. I don't know why I put off changing the filter so long...
