Based on what I have read the main cause for the attempt by Lief Eriksson to start a colony in Newfoundland to fail was from his antagonizing the local Native Americans, who them attacked the settlement in revenge.
What would have happened had things gotten off the ground and a bunch of folks from Iceland (and prehaps even further afield in Norway and the Faroe Islands, hearing of the new land with much better climate than Greenland, settled there. Even a settlement of 5000 people would have been vary sustainable, but more sustainable than the one in Greenland, which would likely migrate to Vinland when the climate deteriorated.
The impact on the Native Americans would be substantial over time. The small population of the Norse settlers would introduce European diseases, but the impact would be small and slow enough not to cause the rapid depopulation like in the OTL and would allow the natives to develop some immunity. Many would also get their hands on iron tools and weapons, and horses, and maybe cattle. Once the Eastern Woodland cultures get how to smelt iron from the Norse that would likely spread to the highly developed Mississippian "Mound-Builder" culture, which at the time was in it's hey-day.
In Europe outside Norway there would not be much effect at first, the main initial impact would be from an increased supply of walrus ivory and polar bear furs. Eventually, though, by the 1200s there would be a realization of the existence of this "new world" among the emerging European intellectual elites. How this would influence the future development of Europe I am not for sure.
I expect the initial colony to expand over time, mostly from natural population increase, and so eventually there will be a small, most likely nominally Christian, Norse state in the region. what would be it's fate?
