How does it feel after changing the spark plug

The function of the spark plug is to ignite the combustible gas mixture and control the lifeblood of the normal operation of the engine. The performance of the spark plug will directly affect the working condition of the engine. So what happens when the spark plug has a problem, and how does it feel after replacing the spark plug?

When there is a problem with the engine spark plug, the specific performance is as follows:

Difficulty starting the vehicle

The engine needs to be ignited several times to start, and if the engine is idling, it is easy to stall. This kind of phenomenon can easily be caused by spark plugs.

Engine idling jitter

When there is a problem with the spark plug, the engine idling state will show obvious and regular jitter. Of course, the engine idling jitter is also very likely to be caused by carbon deposits, which requires us to go to the 4S shop or repair shop to investigate one by one.

Weak vehicle acceleration

When the vehicle needs to accelerate urgently, it will feel that the vehicle is weak in acceleration, and it will be accompanied by engine jitter and fuel consumption increase.

After replacing the spark plug, you will feel that the vehicle has ample power and strong acceleration, and the engine jitter and flameout associated with the replacement before the replacement will disappear, the engine will run smoothly, and the vehicle's fuel consumption will be reduced accordingly.
