On my fiance's Focus this code was given for the vacuum leak it had. There was a tube with a 90 degree bend right off of the pcv. Common problems in the Focus's, don't know much else about the ZX2's, could be the same DOHC 2.0?

Does it have a stumble at idle?

sometimes. sometimes it stalls at lights. I did some research and its just like you said, could be a leak in the pcv line

from what I heard, the pvc line is one of the most common failures on the 2.0 ztech engines....easy to fix, just a little bit annoying
