The Car Is Not Easy To Start in The Morning in Winter, Do I Need To Change The Spark Plugs?

In winter, the temperature is low in the morning, especially in the north, which is much lower than in the south. If the battery power is not enough, it will be difficult to start. And if it is not good to start in the morning, whether to change the spark plug can only be known through inspection. If there is obvious frustration when driving, idling vibration, or when the acceleration performance of the engine declines, you should check the spark plugs, ignition coils and oxygen sensors in time to see if they are working abnormally.
It is difficult to start in cold weather from two situations. One is that when the temperature is high, it will start at one point. As the temperature decreases, it will gradually become difficult to start. It may be that the capacity of the battery decreases in cold weather. Can.
Another situation is that it is not easy to start at ordinary times, and it is even more difficult to start in winter. There are many causes, such as poor ignition coils and spark plugs, sensors related to vehicle computer control, loose or virtual connections of relay plugs, and fuel pressure. Abnormalities, etc., first rule out whether the fuel pressure is normal. Before starting, turn the ignition switch to the ON gear for 2~3 seconds, then turn off the ignition switch, and reciprocate several times. If it can start smoothly, check the fuel pressure system.
Therefore, it is not easy to start in the morning in winter. First of all, the problem of the battery should be ruled out. Whether the spark plug needs to be replaced can only be judged by the actual inspection according to the vehicle condition.
The life of spark plugs At present, there are several types of spark plugs on the market, such as nickel alloy, platinum, iridium, and iridium platinum, and there are different replacement cycles according to their materials. Generally speaking, nickel alloy spark plugs are often used in some low-end models due to their low price, and their service life is about 20,000 kilometers. With the advancement of technology, spark plugs made of materials such as platinum and iridium have become popular, and their service life has become longer, generally about 60,000 to 80,000 kilometers.
Symptoms requiring replacement
According to the question, what symptoms do the spark plugs need to be replaced?
The above spark plug is the spark plug that causes our engine to accelerate poorly. Because the electrode gap of the spark plug is too large, it cannot provide stable ignition energy, and sometimes it may even fail to ignite, so it will cause our car to have no linearity when accelerating. , When we need power, it is like dragging gears. The car is prone to stuttering. This kind of car does not accelerate smoothly. If it feels stuttering when accelerating, the spark plug needs to be replaced.
If you gradually find that your car is more and more fuel-consuming, and the power loss is relatively large, it does not have the smooth feeling of driving before, and it always feels that the car has no strength when accelerating, and it also feels weak when going uphill. It is difficult to go up. In the case of a car like this, we can also consider whether the spark plug should be replaced.
Cold start difficulty
When the weather is cold, we start the car in the morning and find it difficult to start. At this time, we can also consider checking whether the gap of the spark plug is too large and the ignition energy is weak, so that our cold car cannot ignite our mixture.
Engine idling shake
When our engine is idling, because the ignition energy is relatively weak, the spark plug gap is too large and other problems will cause the smoothness of the engine to decline, which will cause our engine to vibrate very much when idling. In this case, we also need to check whether the spark plug needs replace.
