What does black smoke coming out of exhaust mean?
What does black smoke coming out of exhaust mean? Black smoke coming out from exhaust and it wont accelerat... my car is running for half an hour and suddenly black smoke coming out from exhaust and when I accelerate there is no more power it wont accelerate anymore. My car has 155345 miles. Why do I have black smoke coming from my tailpipe? If there is a lack of of air coming into the engine, the fuel will be burnt partially then leads to black smoke from tailpipe. Fuel needs to be burnt fully as it will only emit CO2...
