Hello.

From what you describe it would appear that your vehicle is running rich, which can be caused by a wide variety of issues. A few common causes are a faulty fuel pressure regulator, leaky fuel injectors, a bad fuel pump, or a bad engine management sensor. As engine performance issues can sometimes be difficult to assess, especially on pre OBD II vehicles, I would recommend having the vehicle’s loss of power diagnosed by a professional technician, like one from YourMechanic.
