How much does it cost to clean the throttle nozzle?

Hello, the price is different in different regions, so the business hours are different. If it is cleaned in a 4s shop, the price of nozzle and throttle is around 400 yuan. If it is cleaned in a repair shop, the price will be around 200 yuan. I hope my answer is helpful to you. The throttle valve is cleaned every 15000 km, and the fuel injector is cleaned every 20000 km.
