2G P0442 Small evap leak

[Shipe12]

Ok so I have a CEL P0442 (Small Evap Leak) and my idle has been messed up since this. Sometimes it will be normal, then sometimes it will be low, and then there's the time when it will go from 1500-2000 up and down while sitting in idle. The car drives fine other than that. From these symptoms does anyone know where I should start my investigation. I plan on looking at it this weekend.

Check the vacuum hoses for your emission stuff. I had that code and it turned out that one of the hoses cracked. I just got the Larson kit from RRE and it fixed it. It was better than finding the leaky hose.

Ok anyone know where i can find diagrams or pics inlcuding all the vaccum lines that are in the evap system? O and i already replaced the gas cap so that cant be it.
When i was taking a look around i also noticed that the filler neck has a little leak in it which i am gunna order and replace that, but does anyone think that could be the probleM? i was thinking no because its effecting my idle and im gettting a evap code but i am a noob. Please any suggestions thanks!
