CEL P0441 code, need help diagnosing

For the past few months I have been getting a CEL which gives the code P0441 when checked with a code reader. According to the Mitchell database using info as provided by Porsche, this code means "Fuel Tank Ventilaton Malfunction". The CEL only gets thrown when the car is fully warmed up and when at idle. After researching what little info I could find in the archives here, I found that the fuel cap could be the culprit. So I bought a new fuel cap, reset the light and waited to see what would happen. Today I got the CEL again.
Any other ideas or obvious areas to check before I throw in the towel and let a shop have at it? Any breathers or vacuum lines to check? I am sure that it is not a huge deal compared to some of the other CEL problems folks have here, but having that CEL stare you in the face is not fun.
Any help is appreciated.
