An engine backfire is a literal "explosion" that happens outside of your car’s combustion chambers—either in the intake manifold or, more commonly, in the exhaust system. It occurs when unburned fuel is ignited by a stray spark or extreme heat in the wrong place. Instead of a controlled burn that pushes your pistons down, you get a loud "bang" or "pop" that can sound like a gunshot. In South Africa’s diverse climate, backfiring is often triggered by moisture entering the ignition system during a sudden storm or by "lean" fuel mixtures caused by altitude changes and failing fuel pumps.
A top-rated mobile mechanic will come to your home or office to determine the source and cause of the engine backfiring and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
Backfires generate sudden high-pressure events in the exhaust system, and can do serious damage if left unchecked. Have the car inspected by a professional mechanic as soon as possible.
