Looks as if your getting waaaaaaay to much fuel to the cylinders.Remove the vacuum line from the fuel pressure regulator and see if there is any traces of gas.Could be that or a sensor or ECM.

Check your temperature sending unit. I had this happen and that was causing a rich mixture all the time because it was reading WAY low, car was always on "Choke"
