Dongfeng Peugeot 20 1 1 model 408, that is, 1.6 automatic. The engine is irregularly short of cylinders. What is the reason?

It is a common problem if the cylinder does not work when the car uses high-power electrical equipment. Headlights, rear window defrosting, car air conditioning and other devices that consume more electricity may cause a cylinder to stop working. The main reason is that the voltage drops too fast in a short time, which leads to the ignition coil not working normally, and it may also be related to the battery power loss. If this happens again, you can turn off the electrical equipment and try to see if this problem will be eliminated.
