How long does it take for Fukang Liuguo 3.8 engine to clean the throttle?

Clean the throttle every 20,000 to 40,000 kilometers.

Failure to clean the throttle for a long time will lead to the deviation of throttle opening, and air with impurities will enter the combustion chamber of the engine. Both of these results will lead to abnormal engine operation, mainly manifested in unstable idle speed, sudden feeling of throttle when driving, power decline, and even difficult starting and increased fuel consumption.
