What symptoms will appear when the car throttle is dirty?

[DelGia]

When the car throttle becomes dirty, it will cause unstable idle speed, reduced power, and difficulty in starting. Unstable idle speed: The dirty throttle of the car leads to changes in the power of individual cylinders, resulting in an imbalance in the power of each cylinder, causing the car to have unstable idle speed. At this time, it is necessary to clean or replace the throttle in time. Reduced power: A dirty throttle will directly affect the accuracy and smoothness of the engine's air intake. The amount of air entering the combustion chamber is greatly reduced, the combustible mixture in the engine becomes too rich, and the ignition energy decreases, leading to reduced car power. At this time, it is necessary to clean or replace the throttle in time. Difficulty in starting: A dirty throttle may cause errors in the throttle opening, allowing air with impurities to enter the engine combustion chamber, making it difficult to start the car. It is necessary to clean or replace the throttle in time.
