Should Unstable Idle Speed Be Repaired?

[ElisaLee]

Unstable idle speed does not necessarily require immediate repair. One of the most common causes of unstable idle speed is severe carbon buildup in the throttle body. Cleaning the carbon deposits in the throttle body can be an effective solution. Causes of carbon buildup: Gasoline contains impurities to some extent, and the air drawn into the combustion chamber also carries impurities. When the combustible mixture of gasoline and air burns, some of these impurities that cannot be completely burned will form sponge-like carbon deposits. Part of the carbon deposits adhere to the combustion chamber and piston surfaces, while the rest is scraped by the piston into the crankcase below. Methods for cleaning carbon deposits: Adding fuel additives to the fuel tank can help. If high-quality fuel additives with cleaning effects are used regularly over time, they can also contribute to removing carbon deposits.
