Stalling at stoplights

I have a 1999 9-3 and I've had this problem of stalling at stop lights. I have read through some posts to help diagnose the issues, but am still coming up short. I've checked the idle control valve and evap purge valve and they both seem to be working fine. I was able to disconnect the line going to the evap canister and it solved the stalling problem so I figured that might be old so I bought a new one and installed it, however the stalling returned. I can disconnect the line to the canister and when it sucks air the car runs fine. when I plug it up, it will hesitate but recover, however when I reattach the line going to the canister it will stall. I sucked on that line and the vapor coming from it doesn't seem like a lot. Is there something else that would affect the fuel/air mixture when the purge valve pulls the fumes from the canister?
