Do you need to clean the throttle valve for CRV 20,000 km maintenance?

First of all, the cleanliness of the throttle depends on whether the actual situation needs cleaning (this is related to the air quality and oil quality of the vehicle environment); Secondly, there is no harm in brushing your teeth several times (brushing your teeth twice a day is better than brushing your teeth only once), but it costs more money. Due to the quality of oil products, the nozzle is easy to stick glue near the spray hole during use. It is best to clean it regularly in a disassembly-free manner to avoid damaging its seal with the intake manifold during disassembly. For more than ten years, several of my cars have been cleaning the fuel lines, injectors, intake manifolds, valve chambers and combustion chambers regularly by adding fuel additives to the fuel tanks (using 5 bottles of additives continuously for each cleaning). They have never been disassembled and cleaned, and the injectors have never had any problems. "Haote" fuel additive is in 75 yuan (a pack of 5 sticks). I spray-clean the throttle myself. Remove the imported corrugated hose connected with it, and spray the throttle plate, door shaft and four walls with cleaning agent. I cleaned the throttle and nozzle five or six times for 600 yuan, so there is no need to send money to the 4S shop. Go to the oil online forum website to check the answer details >>
