What is a "backfire"?
A backfire is a situation where a vehicle's engine produces a loud popping or explosive sound, often due to a problem with the combustion process. This occurs when fuel ignites in the engine's exhaust system or outside the combustion chamber. Backfires can be caused by issues like incorrect timing, a dirty fuel system, or engine failures. While backfires can be alarming, they are usually not dangerous, but they may indicate the need for repairs or adjustments to the engine to prevent further problems.
