Symptom of failed ELCD purge valve

I've been having rough idle issues for a couple weeks when the engine was warm or cold so I cleaned the IAC and ELCD purge valve for the first time. When that didn't solve the problem I checked the hoses and found the hose between the throttle body and purge valve was cracked. When this hose was replaced the rough idle with warm engine was solved, but not when cold. Checked all the hoses again, but all looked good. Only thing I've noticed is that I can no longer hear the purge valve clicking when the engine is warm.
Would a purge valve stuck open cause a rough idle when the engine was cold?
