This small part – the spark plug. Don’t underestimate it, but if it has problems, your car will “change its temper” in a minute.
Especially when the spark plug is aged or damaged, the vehicle’s starting, acceleration, and fuel consumption will be affected, and in severe cases, it may even cause the engine to pull the cylinder, which is not a trivial matter.
Today, let’s talk about the three symptoms of the car when the spark plug should be replaced!
Symptom 1: Difficulty starting
If you go out in the morning and find that it is extremely difficult to start the car, it is likely that there is something wrong with the spark plug.
The main function of the spark plug is to ignite the mixed gas in the engine and allow the fuel to burn fully.
If the spark plug is aged and the ignition energy is insufficient, it will become difficult to start the engine.
Suggestion:
It is a good habit to check the spark plugs regularly. Generally speaking, nickel alloy spark plugs are recommended to be checked every 20,000 kilometers. Iridium and platinum spark plugs have a longer lifespan, which can be extended to 60,000-80,000 kilometers.
Symptom 2: Poor acceleration
If you press the accelerator to the bottom and the car moves slowly, it is probably because the spark plug has stopped working.
When the spark plug is working properly, it should be able to provide sufficient ignition energy to allow the engine’s fuel to burn fully. However, if the spark plug is aged or faulty, the ignition will be unstable, which will affect the power output and the car will have difficulty accelerating.
Suggestion:
If you find that your vehicle has a weak acceleration, especially when overtaking on the highway, you should check the spark plugs immediately and replace them with new ones.
Symptom 3: Fuel consumption Increased
The mileage remains the same, but the fuel consumption keeps increasing? The problem is most likely with the spark plug. When the spark plug is damaged, the combustion efficiency will drop significantly, the fuel will not burn completely, and the fuel consumption will increase directly.
Suggestion:
When fuel consumption suddenly increases, you may wish to check the spark plugs first. Replacing the spark plugs with new ones can not only restore fuel consumption to normal, but also reduce exhaust emissions, which is environmentally friendly and saves money!
Conclusion
Spark plug problems may seem minor, but if not solved in time, it may lead to more serious failures. In order to avoid engine damage, it is necessary to check the spark plugs regularly.
