How to clean Chevrolet Lefeng carbon set? How much will it cost?

Hello, according to your situation and our maintenance experience, if your vehicle is Lefeng, I suggest you clean the accelerator and idle motor of the vehicle. If the carbon deposit in the air inlet is to be cleaned, it is best to remove the air inlet manifold and clean it thoroughly. Generally, the cost of cleaning throttle and idle motor is around 50 yuan. If you fall into the air manifold, the cost will probably be around 300 yuan. I hope my answer will satisfy you. Have a nice trip. If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
