A car backfires when unburned fuel ignites in the exhaust system or intake manifold, typically due to issues such as incorrect air-fuel mixture, faulty spark plugs, or a malfunctioning ignition system. It can also occur if there are exhaust leaks or if the timing of the engine's firing is off. These conditions lead to delayed combustion, resulting in a loud popping sound. Regular maintenance can help prevent backfiring issues.
