Why does my classic car backfire?

Reason #1: Bad Engine Timing. An engine backfire is what occurs when the combustion event takes place outside the engine’s combustion cylinders. If the timing of the spark is a bit too late in the engine cycle, unburnt fuel and air may be allowed to flow through the exhaust.

Do old cars backfire?

If your car is old, the carburetor manages the mixture of air and fuel, which is a common culprit for backfiring. If your car is newer, it has a computer called the engine control unit that manages everything. The ECU could therefore be the problem, or the mass airflow sensor.
