Hey Guys,

96 Contour Zetec 4cyl 150.000km bin idling rough/rolling especially when cold. Sometime stalls but start up quickly, drives fine at highway speeds. I found the breather hose disconnect from the valve cover about a month ago, seems the dealer forgot to reattach it after a water pump job.
Tub has been disconnected for over 3 months. Any relation between the two???

Thanks Laziale
