What is an Engine Misfire?

Your car's engine starts through fuel and air combustion inside the cylinder. Most modern vehicles have at least four cylinders to keep running even when one fails. However, not at its full potential. This failure may cause an engine to misfire.

What's A Misfire?

A spark must trigger the combustion of fuel and air compressed inside the cylinder in the correct order. If this sequence fails or any element is missing, the burning reaction will not occur. This combustion failure is called a misfire. The engine cylinders must fire in a precise sequence. Otherwise, it remains unfired.

Generally, a misfire is incomplete combustion inside the cylinders. It can happen during startup or when the engine is idling. While most misfires dissipate and your engine may regain full power, it usually signals an underlying problem. Multiple misfires put your engine's components under mechanical strain and may cause bigger issues if unchecked.

However, when your car misfires, the check engine light turns on usually by flashing. A solid engine light may signal a minor problem, but when it's flashing, it indicates a severe problem.

Causes of Engine Misfiring?

With modern gas engines, misfires are the most common problem. But, there are several potential causes. Here are the most common.

  • Ignition system problems

The ignition system has various parts, including the control module, such as the coil packs, wiring, spark plugs, and crankshaft position sensor. If any develops a problem, it causes a misfire.

  • Fuel and air delivery issues

Combustion requires an air and fuel mixture. Any issues interfering with the process, such as failed fuel injectors, may result in a misfire.

  • Emission equipment issues

Emission equipment minimizes atmospheric pollution from your car. These may include positive crankcase ventilation (PCV). When it becomes problematic, a misfire may occur.

  • Engine problems

Engine problems linked to misfiring include pistons failing to compress air and fuel to complete combustion. This interferes with the process causing misfiring.

  • Control circuit issues

Engine management devices such as sensors are electrically connected. An engine misfire happens when circuit problems like loose connections or damaged wires occur.

Regular maintenance helps prevent misfiring. But, when your engine misfires, address the problem immediately to avoid more complications. Bring your car to Crossroads Tire Service for engine repairs.
