what happens when your CAR blows BLACK SMOKE

In this short video, we'll tell you what happens when your car emits black smoke. Black exhaust smoke means your engine is burning too much fuel. The first thing to check is your air filter and other intake components, such as fuel injectors, sensors, and the fuel pressure regulator. Other causes could include a clogged fuel return line. Black smoke is often the easiest problem to diagnose and fix, but burning unnecessary fuel will definitely affect your fuel economy, so don't try to avoid it to save money—it won't work. Any smoke coming from your car's exhaust pipe is a sign that your car is in trouble. Pay attention to what you need to ensure longer mileage for your vehicle.
