after a tank of gas it started bobbling. We have changed the fuel filter 2 times. Now we just changed the fuel pump and strainer. Now it is still running really weird and blowing out black smoke. I'm not sure what to do next. Do you have any suggestions?

Check your fuel pressure if okay could be an injector leaking or the fuel pressure regulator to include a defective coolant temperature sensor/oxygen sensors and excessive fuel pressure.
