Great Wall c30 engine throttle is in that place, how to clean it?

Hello, the lid is open. There is a black hose with a diameter of about 5 cm. One end is on the air filter box, and the other end is the throttle. The approximate position is in the front position between the gearbox and the engine. If you clean it, you must go to the repair shop, and the professionals will help you clean it. Dirty throttle will lead to unstable idle speed during driving, difficult starting and easy flameout when braking.

I hope the above answers can help you. Have a nice ride! If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
