O2 sensor
Coolant temp sensor
Manifold air temp sensor
Excess fuel can also be attributed to faulty injectors or fuel reg.
Any codes ??

What does the smoke smell like?

Is the service engine soon light on?

Noticed any changes lately and the black smoke is a symptom?

More info and we might be able to narrow it down for you.
