I own a 2005 Nissan Pathfinder which hesitates between 35 to 40 mph and sometimes around 60 mph as if to cut off (running rough). When I take my foot off of the gas pedal the engine runs smoothly. There is no check engine light on but I can pull diagnostic code B0F59. I've tried several automotive shops and looked on line to find out what this code means with no luck. Can any one tell me what this means?
