Spark plugs play a critical role in igniting the air-fuel mixture that triggers your engine's internal combustion process. Running your car is impossible without this inexpensive yet unsung hero in your vehicle's ignition system. Like other vehicle parts, spark plugs need routine servicing and maintenance. While they are responsible for starting your car engine and driving, sometimes they fail and will need replacing.
Symptoms of a Failing Spark Plug
Experts agree that spark plugs must be clean without damaged electrodes for optimized performance. Driving with a foul or failing spark plug can lead to many problems. But first, you must know the symptoms of a faulty or failing spark plug.
When starting your car becomes challenging, the spark plug could be faulty. This is primarily the main symptom of a failing spark plug. The problem occurs when the spark plug fails to produce sustained ignition for the combustion process. It is recommended to replace it immediately.
Slow acceleration in most cars is usually linked to a faulty ignition system. While the problem may also be a failing sensor, a worn-out or a bad spark plug is the most common cause. A worn-out spark plug has reduced effectiveness and lowers your vehicle's acceleration.
Check your spark plug if you begin noticing your car's acceleration reducing. But make sure an expert handles the problem.
When your car's spark plug is well maintained, it ensures fuel burns efficiently to sustain the combustion cycle. However, your spark plug is probably worn out when you notice an increase in fuel consumption. When the plug fails, the ignition gap becomes too close or far, requiring more fuel.
In most modern cars, a misfiring engine is due to a faulty sensor. But in most cases, it is also a malfunctioning spark plug. The problem arises when the tip connecting to the spark plug wire is damaged. Misfiring is usually noticed through an intermittent spluttering or stumbling sound from the engine. It also causes an increase in exhaust emissions and a drop in fuel economy.
- Engine Surge or Hesitation
A sudden surge in power followed by slowing down or hesitation during acceleration could indicate a spark plug problem. The problem occurs when more air is sucked in than required, causing a delay in power transmission.
