Backfiring Exhaust Causes

Backfiring Exhaust Causes Miracle Body and Paint San Antonio Texas

Miracle Body and Paint San technicians receive a lot of vehicle-related questions every day. Backfiring exhaust system seems to raise a lot concern. At Miracle Body and Paint San Antonio, we want our clients to have peace of mind so we’ll be answering some questions about backfiring.

A backfiring exhaust typically sounds like a gunshot similar to a “cough” or a “sputter”. Although an engine backfire or “aftercare” (if it occurs when the engine has already been shut off) will not harm your vehicle, it can still be very inconvenient and may interrupt your peaceful driving. Reasons why this happens include:

  • Your engine decelerated too quickly
  • Your gasoline in your car consists of  high levels of alcohol
  • Your engine is overheated
  • A spark plug refuses to “spark”. When this happens, the air/fuel mixture becomes too rich and unburned fuel is left in the exhaust system. When the misfired spark plug finally ignites the rich air/fuel mixture, a loud “bang” in the  tail pipe happens

Our highly trained auto mechanics at Miracle Body and Paint San Antonio will inform you the exact reason why the exhaust is backfiring.

A backfire can get loud and highly intrusive. Fortunately, there are a few ways to cure this. A few ways to stop a backfire are listed below:

  • Make sure to lower the engine speed gradually
  • Pick a fuel brand with lower alcohol levels
  • Lower engine temperatures by adjusting the carburetor
  • Ask out specialists if your air volume needs to increase to prevent backfiring due to air/fuel mixture.

Our highly trained technicians at Miracle Body and Paint can check your exhaust system and relieve any airway constriction. This will increase the engine-cooling air volume and eventually minimise the risk of a backfire. Make sure to contact us and schedule exhaust system service with Miracle Body and Paint. Even if a backfire from the exhaust pipe won’t ultimately hurt your car, it can still  be scary and loud. Make sure your car is performing at its best by scheduling an exhaust system inspection at Miracle Body and Paint in San Antonio, Texas today.
