What is the reason for the white spark plug and weak acceleration?

Reasons for white acceleration of spark plug: 1, oil circuit fault Many people think that carbon deposition on throttle will affect the acceleration performance of engine. However, I think that the carbon deposition in the throttle only affects the idling instability, but has little effect on the acceleration performance of the engine; 2, air filter blockage or water intake will make the air volume smaller, resulting in too rich mixture, engine acceleration will not be smooth, and the exhaust pipe will emit black smoke seriously at this time; 3. Tubing rupture or loose and leaking joint, insufficient oil pump pressure, poor oil supply, poor acceleration, poor atomization or blockage of injector, resulting in poor or non-working cylinder. Affect the acceleration performance. The exhaust pipe may emit black smoke; 4. The oil problem is also one aspect. If the water content of the oil is too high, the exhaust pipe will emit white smoke; 5. Circuit failure The problem of air flow meter leads to the decrease of air intake, which leads to the mixture being too rich or too thin and affects the acceleration performance. In other words, the spark plugs of individual cylinders are damaged, which means that the lack of cylinders affects the acceleration performance. There is also a leak in the cylinder pipeline and so on.
