Why does the car lack power when starting?

[DeDaisy]

Car starting with lack of power can be divided into two situations: one is a normal phenomenon, and the other is a malfunction. Under normal circumstances, the lack of power when starting the car may be due to a cold start. A cold start means stepping on the accelerator abruptly when the engine is cold, which will cause the vehicle to accelerate slowly. This is a normal phenomenon and a kind of protection for the engine and other components. It may also be due to heavy load. This is because after driving alone for a long time, suddenly carrying a heavy load can also result in insufficient power. There are many reasons for the lack of power when starting the vehicle. If black smoke comes out of the exhaust pipe, it may be caused by a faulty oxygen sensor, which requires replacement for a test drive. It could also be due to poor valve sealing or insufficient cylinder pressure causing the lack of power when starting. And so on.
