It is not good to start cold in winter. Can you make a hole in the accelerator?

Cold start in winter is not good, and it is easy to make a hole in the throttle. According to relevant public information, opening a hole in the throttle can keep warm in winter, but it may affect the normal work of the engine, especially in the case of high speed and high load. Therefore, it is suggested that the method of drilling a hole in the throttle to keep warm should not be used easily, and the engine should be maintained according to its performance to ensure its normal work.
