What are the precautions for cleaning BMW x3 accelerator?

There are many precautions for cleaning the BMW x3 accelerator. First of all, the cleaning agents we buy are generally very corrosive. The choice of cleaning agent is particularly important. Do not use strong corrosive cleaning agents. When cleaning, pay attention to the cleaning strength to avoid damaging the coating. Throttle fouling is mostly caused by poor air quality and poor oil quality. Due to the negative pressure, the carbon deposit generated in the process of gasoline combustion will interfere with the throttle valve and make it not close well, thus increasing the intake air, causing signal transmission errors, leading to high fuel consumption and engine idling jitter. Therefore, during maintenance, be sure to check the throttle opening. If it exceeds the normal range, it should be cleaned. 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 a polyester rag or high-count non-woven fabric. Deep in the throttle valve, where the hand can't reach, take a rag and scrub it carefully. After cleaning, install it in reverse according to the procedure just removed. After installation, the throttle valve will be initialized.
