Guys! My Acura NSX oxygen sensor is not in good condition, there's a black smoke from the exhaust and like a rotten-egg odor on it. How can I fix my car?

Sounds like a bit more than just an oxygen sensor. You could be looking at a failed cat/s?

You can get the emissions tested at any old garage or MOT station but you may have to take it to a specialist or Honda dealer to get advice on exactly what's failed and needs replacing.

Where are you located, the fact that you said Acura suggests the USA?
