How much does it cost to clean up the carbon deposit in the car engine?

Hello, I'm the editor of Automobile Maintenance. Glad to answer this question! How much does it cost to clean up the engine carbon deposit? The price of this cleaning part is also different. Basically, the price of carbon deposit per cleaning is around 150 yuan. For example, the carbon deposit in throttle cleaning may cost only tens of dollars. Of course, many luxury cars are more troublesome to clean, which may require more labor costs! Pay attention to how to clean up the carbon deposit: 1. Throttle carbon deposit! This is easy to clean and operate. Clean up the carbon deposit near the throttle with throttle cleaner! If it is a cable throttle body, it is necessary to focus on cleaning the idle motor! 2. Clean up the carbon deposit in the combustion chamber! Put the cleaning agent into the combustion chamber so that the cleaning agent can fully soak the piston. After soaking for 30 to 40 minutes, recover the cleaning solution, so that the carbon deposit on the piston will be washed away! 3. There is carbon deposit on the intake pipe! The cleaning method of intake manifold is similar to that of throttle. The most direct and effective way is to take it out and put it into the ultrasonic cleaning pool for cleaning! 4. Clean the fuel injector! This also requires special ultrasonic cleaning and electric cleaning of the fuel injector to make the cleaning more thorough! For carbon deposition cleaning, the most important thing is to clean up the above four parts. Too much carbon deposition will cause problems such as unstable idle speed, knocking on the cylinder and slightly difficult cold start!
