How often must the car throttle be cleaned?

Under normal circumstances, it is recommended that the owner clean the throttle every 20-40 thousand kilometers, but this is just a reference value for everyone. The specific cleaning cycle depends on the air environment of individual cars, the type of oil used, the interval of changing air filters and driving habits.

There are no phenomena such as unstable idle speed, engine jitter, obvious increase in fuel consumption and weak acceleration. It is best to clean it.

For example, if you drive on dusty roads, the throttle will definitely be dirty, and it may be cleaned within 20,000 kilometers.

Precautions for cleaning throttle valve:

First, apply a little oil on the fixed metal beam ring to avoid slipping teeth during disassembly. Remove the metal wire harness ring of the throttle hose. After the hose is removed, the left end is the position of the throttle. Remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, spray a small amount of "carburetor cleaner" into the throttle, and then carefully scrub it with polyester rag or high-spin "non-woven fabric". Deep in the throttle, you can hold the rag and scrub it carefully where your hands can't reach it.

When cleaning the throttle valve, it is not necessary to disassemble it, but the sealing part of the inlet steam must be cleaned, and the idle motor must be disassembled for cleaning. There are advantages and disadvantages of cleaning nozzles by borrowing and disassembling. Generally speaking, the maintenance station suggests disassembling and washing, which can prevent other unnecessary waste, such as replacing the sealing ring after disassembling or installing other gaskets, or delaying the owner's time because of oil and gas leakage when disassembling.
