What are the common problems after cleaning the accelerator?

After cleaning the throttle, it is easy to have unstable idle speed and increased fuel consumption, which is generally caused by the throttle opening not being reset. Because the throttle is squeezed by carbon deposit, the opening of the throttle will expand. After cleaning, if it is not reset, the throttle opening will remain in the state before carbon deposition, and the air intake will increase, which will lead to unstable idle speed, too high speed and increased engine fuel consumption.

Under normal circumstances, the throttle valve is cleaned once after driving for about 20,000-30,000 kilometers. It can be cleaned with a special foam cleaner or by removing the throttle valve. However, 4S shops or repair shops usually use hanging bottles for cleaning-when the engine is running, the cleaning liquid is continuously sprayed into the air inlet. Although it takes a long time, it is relatively simple to operate, and you can also clean the air inlet by the way.

Precautions:

When cleaning the throttle, first remove the intake throat to expose 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-spinning non-woven fabric. The deep part of the throttle that the hand can't reach can be carefully scrubbed with a clip.

When removing the throttle, some air pipes are connected around the throttle. We need to remove these pipes. When disassembling them, be sure to remember the position of each pipe for installation after cleaning.
