It could, if it's leaking.
Black exhaust smoke is a sign of an injector needing a service.
If its BLACK smoke it's unburned fuel. If it has carb, the carb float is too high or sunk. If it has fuel injection it's a stuck (open) fuel injector.
sounds like a stuck fuel injector
how can i get black exhaust smoke stuck on my dual exhaust
emissions and exhaust
blown turbo - worn turbo bearing causing oil to suck through and into exhaust manifold - results in no power and neat oil burning in the exhaust - major black smoke
It is buring oil this is a wrong answer whe engine burn oil to the exhaust smoke is a heavy white smoke no black
If the smoke is black it could be caused by a faulty fuel pressure regulator which could be causing the engine to get too much fuel.
Black smoke is a sign of a vehicle running rich. I would check for a bad fuel pressure regulator, bad fuel injector or very plugged air filter. A fuel pressure test could tell you much.
Service engine
