If there is too much sludge in the accelerator, it may cause poor engine acceleration and increase fuel consumption, which is a big worry for the owner. What should I do if the throttle is dirty? Just clean it up Go to the 4S shop, the throttle will be repaired soon, but you don't have to go to the 4S shop to clean it every time. Actually, you don't have to. You can do it yourself, just don't forget to initialize it.

2. Apply a little oil on the fixed metal beam ring first to avoid the teeth slipping during disassembly. Remove the metal wire harness ring of the throttle hose. After the hose is removed, the left end is the position of the throttle. Remove the negative 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-spin "non-woven fabric". Deep in the throttle, you can clamp the rag and scrub it carefully where you can't reach it.
