I was wondering if anyone has had the same thing happen to them as I do. My 5.0 is idling ruff and blowing black smoke out the tail pipe. Is smells like it is getting to much gas and the plugs are black. But it still starts. When you put power to it, It seems to run fine. When it is idling, the RPM'S are down and when you are driving it, It stalls when you stop. It starts right back up. I have tryed a few things like new o2 sensors, It has new plug wires, new plugs, new fuel pressure regulator.
