What causes a vehicle to backfire and how dangerous is it?
In: Other
You need to make sure you distinguish afterfire and backfire. What you usually hear in sports cars (or tuned cars) is *afterfire* where extra fuel is burned in the exhaust and creates a loud pop/bang. This is not dangerous, just wasteful of fuel and could mean the car is running inefficiently if it’s not intentional.
Backfire is when combustion occurs in the intake portion (ignition travels backwards, hence the name). This is very dangerous to the engine’s longevity and can significantly reduce power, but it will not cause the car to explode or anything like that.
