The first thing I'd look for is an exhaust leak. It would facilitate the exhaust fumes entering the cabin, and if the leak is before the 02 sensor it could be sucking in fresh air leading the sensor to misread as a lean condition thus adding more fuel. Other possibilities could be a cold start enrichment gone awry, but I don't know enough about 960s to pinpoint what could cause that.
