CAR ENGINE MISFIRES

02-Jul-2024

An engine misfire is a malfunction, during which one or more of its cylinders are not working. It causes excessive wear and overheating of the engine, and leads to scuffing of the surfaces of pistons and cylinders. In the following we’ll explain how to recognize this problem and how to fix it.

SIGNS OF MALFUNCTION

  • Engine jerks at idle. Sometimes the vibrations are so strong that you can feel them in the steering wheel, gear lever, and car body. In addition, the idling rotational speed of the engine is unstable.
  • Reduced engine power. You may particularly notice malfunctions in engine operation when you press the accelerator pedal, as well as jerks on acceleration. The ‘Check Engine’ indicator may light up on the dashboard.
  • Unusual sounds when the engine is running. For instance, intermittent sounds can be heard instead of a steady hum.
  • Increased fuel consumption. This is typically caused by problems with the fuel mixing and ignition processes.
  • Carbon deposits on the spark plugs and cracks in the high-voltage wires. These are usually easy to spot when inspecting parts.
