Engine misfire, an irregular engine running, can frustrate any car owner. This article explores the causes, diagnosis, and solutions to this annoying problem, helping you get your vehicle running smoothly again.
What is “Misfire” in a Car?
“Misfire” describes an erratic engine operation characterized by jerking, sputtering, and power loss. The engine runs unevenly, as if it were “sneezing.” This phenomenon can have various causes, ranging from simple ignition problems to more complex malfunctions in the fuel injection system.

Causes of Misfire
The causes of misfire are varied and can differ from vehicle to vehicle. Common reasons include:
- Faulty spark plugs: Worn or fouled spark plugs can disrupt the combustion process and lead to misfires.
- Faulty ignition coil: A defective ignition coil may not correctly transmit the ignition voltage to the spark plugs, leading to misfires.
- Fuel injection system problems: Clogged fuel injectors or a faulty fuel pressure regulator can impair fuel delivery and cause misfires.
- Vacuum leaks: Leaks in the intake system can lead to an incorrect air-fuel mixture and thus cause misfires.
- Defective mass airflow sensor: A faulty mass airflow sensor provides incorrect readings to the engine control unit, which can lead to incorrect mixture formation and misfires.
Diagnosing Misfire
Diagnosing misfire requires expertise and specialized diagnostic equipment. A workshop can read out the fault memory and check the relevant sensors and components. Dr. Karl Schmidt, author of “Modern Vehicle Diagnostics,” recommends a systematic approach, starting with checking the ignition system and the fuel injection system.
Solutions for Misfire
The solution to a misfire problem depends on the specific cause. In some cases, it is sufficient to replace the spark plugs or the air filter. For more complex problems, repair or replacement of components such as the ignition coil, fuel injectors, or mass airflow sensor may be necessary.
Benefits of Troubleshooting
Early detection and resolution of misfires protect the engine from further damage and ensure optimal fuel consumption. It also improves driving performance and comfort.
