Hey guys.... I need some help please. I have a 95 Maxima that repeatedly stalls out on me while driving and at stops. It also poors out black smoke when trying to restart. The engine light is on now, but it seems to come on and off when it wants to. I did replace my starter and it made a difference when I do start it, but this stalling thing is crazy. No one seems to know anything. It must be something common enough for a Nissan mechanic to figure out. PLEASE HELP !
