Solutions to unstable idle speed of automobiles.

Clean the throttle first. If the problem still exists, according to the specific reasons, increase the speed to clean up the engine carbon deposit, or replace the spark plug, engine air filter and fuel filter.

80% of the car's idling instability is caused by dirty throttle or carbon deposition in the engine. It may also be that carbon deposition or spark plug aging affects the ignition efficiency, or the engine air filter is too dirty and the oil circuit is not smooth. Just clean the throttle, replace the spark plug and replace the engine air filter or fuel filter. If the carbon deposit is serious, you must go to a professional garage to clean up the carbon deposit in the engine, and don't waste money.

It is recommended to replace the engine air filter every 20,000 kilometers and clean the throttle. Cars in harsh environment (construction site, desert) can be replaced and cleaned once every 10000 km. The throttle valve is located behind the engine air intake. You can basically find the throttle valve by finding the engine air filter element.

Poor oil circuit: During the storage, transportation and filling of fuel, some impurities and moisture will inevitably be mixed. As the fuel enters the automobile fuel supply system and the engine cylinder, the cylinder will accelerate wear. Before entering the gasoline pump, the gasoline must be filtered to ensure the normal work of the gasoline supply system. At present, most engines are basically disposable paper filter gasoline filters, and the replacement cycle is 10000 km.

If the center electrode of your car spark plug is nickel alloy, it is recommended to change it every 20,000 to 30,000 kilometers. If the center electrode and side electrode of your car spark plug are basically platinum or iridium, it is recommended to replace them every 80 thousand kilometers, and clean up the carbon deposit of the spark plug immediately if necessary; If your car spark plug is only the center electrode, which is made of platinum or iridium, it is recommended to replace it for 40,000-60,000 yuan.
