After Cerato washed the accelerator, the click was louder than before. Is it normal?

You didn't initialize it! Cleaning the throttle needs initialization, although you didn't remove it. But you pulled out the intake pipe! It's normal to be loud at first. It's not normal if it's still midnight all day. Suggest initializing it. In fact, initialization is very simple. You can do it with a special computer or by hand, but it is not as fast as a computer, and sometimes it will fail. It doesn't matter if you fail. Do it again. According to different vehicles, there are two ways to initialize: the first way is to turn on the key to the second gear, that is, the gear indicated by the instrument is fully lit, then wait for 20 seconds, press the accelerator to the bottom and hold it for about 10 second, then release the accelerator, turn off the ignition switch, and pull out the key to complete the initialization. The second is to turn on the key in the second gear and hold it for 30 seconds, then turn off the ignition switch and pull out the key. It should be noted that after the two methods are completed, it will take some time to try to ignite. Generally, you can wait 15-20 seconds, and then ignite to see if the refueling is normal and the engine fault light is off. If at first you don't succeed, you can do it again until you succeed. You can usually succeed once, at most twice. But according to different cars, the method of restoration is different. Some cars must be initialized by a computer. In that case, the owner is advised to send the car to a shop with professional equipment for cleaning.
