My car is running super rich. It gets to the point where it starts getting more and more smoke and eventually it just poors out the exhaust. Can i diagnose whats going on with hp tuners scanner, or do I need something else to diagnose it? How can I see if one injector is dumping more fuel then others? Any ideas how to tell if an injector is stuck open?

Any suggestions would be welcomed, been having this issue for quite a while.
