I believe your car has the 4.1-Liter fuel injected V8. How does it idle? My guess is that one or more fuel-injectors are leaking/dumping fuel, which is why you see black smoke or unburned fuel. Pull the spark plugs. If some plugs are clean while one or more are carbon fouled this indicates too much fuel where the fouled plugs are. You might be able to pinpoint bad injector(s).
