Engine backfires are one of the most obvious symptoms of car trouble, and they are annoying and potentially damaging to the car’s exhaust and catalytic mechanisms.

Backfires occur for various reasons, and may be accompanied by a Check Engine light.

Common reasons for this to happen:

  • When moisture or resistance in the car’s electronic ignition system allows a crossover generation of current to the wrong cylinder.

  • A lean mixture caused by either an engine vacuum leak or low fuel-pump pressure.

  • A faulty air injection check valve (part of the car’s emission control system) allows too much air into the car’s exhaust system.

  • A failed air intake boot can cause a backfire by altering the feedback voltage to the PCM.

  • Faulty ignition components or spark plugs may also cause backfires if the ignition timing drifts off or the plugs fire intermittently.

  • An exhaust leak such as broken welds or other small holes can take in cool air during deceleration and cause a popping or backfiring in the exhaust system.

What to expect:

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.

How important is this service?

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.
