Everything to Know About Engine Misfires

An engine misfire occurs when one or more cylinders can not deliver enough power. Drivers often describe the feeling as a jerk coming from the engine. When your engine misfires, it always triggers the check engine warning light to come on your dash. Additionally, you may experience sluggish acceleration or rough idling. 

Unfortunately, engine misfires can be challenging to diagnose without professional help. Various factors, from malfunctioning oxygen sensors, dirty fuel injectors, and worn spark plugs, can cause engine misfire.

Common Types of Misfires

  • Spark Misfires - As the name suggests, this type of misfire occurs due to worn or failing spark plugs. These small metallic components are in charge of starting the combustion process, and they wear down over time. If you are experiencing a misfire due to spark plugs, please ensure you replace them soon.
  • Fuel Misfires - A clogged fuel filter or filthy fuel components can also make trouble for your engine. Fuel-related misfires can happen unexpectedly and usually ensue when the engine is idling rather than driving at high speeds. Please bring your vehicle to Elite Auto Experts for a fuel system inspection once you notice this symptom.
  • Mechanical Misfires - Mechanical misfires are highly destructive and complex. This umbrella of misfires can be caused by various failing parts. For instance, engine combustion can be disrupted by a slipping timing belt or faulty sensors. Broken valve trains and compromised vacuum lines also cause a mechanical misfire. This type of misfire is suitable for diagnosis by a professional auto mechanic.

If your vehicle is suffering from misfires, please do not wait to give it attention. You can end up hurting the engine more by neglecting an inspection and repairs. Instead, we invite you to Elite Auto Experts so that our certified technicians can properly diagnose the cause of your misfiring issue.
