Evaporative Emmission Control Leak Code
#1

Had radiator replaced in my 1998 Volvo V70 GLT (165,000 miles). I am now getting an engine code (455) Evaporative Emission Control System Leak (Gross). Along with this code, the car runs extremely rough for 10-15 seconds when starting cold, almost like it is choking itself out. After this initial startup it seems to run fine. When replacing radiator, it is highly likely that vacuum lines were disturbed. Such as those from the Purge Valve (attached to radiator shroud) ect. Anyone have any ideas of items to check?

I had someone change the radiator, so I do not know if I have a hose missing or not hooked up correctly. Without a good diagram showing where all the hoses run, it's making it difficult to pinpoint any vacuum problems.
One thing I did notice though, is the purge valve has a hose coming in one side, with a filter right below it, but no hose connected to the other end. Also there is another hose coming off the manifold (close to the purge valve) that "tees" with one of the ends not hooked to anything or plugged, pulling a huge vacuum. I need to find out if these should both be open or connected to something? This is where a good diagram would be useful.
