What causes the lack of power when accelerating in Haval H6 Coupe?

[Lester]

The reasons for the lack of power when accelerating in Haval H6 Coupe are as follows: Ignition system malfunction: For example, aging ignition coils or spark plugs that have not been replaced for a long time can lead to insufficient ignition energy, poor combustion, weak engine acceleration, and the engine malfunction light turning on. Fuel system malfunction: System failure causing low pressure and insufficient fuel injection, resulting in weak engine acceleration. Excessive engine carbon deposits: Leading to poor fuel atomization, which also causes poor combustion, excessive exhaust emissions, and weak engine acceleration. Engine system malfunction: Causing the engine to enter emergency operation mode, thereby limiting engine power output and resulting in weak acceleration. Examples include engine sensor failures such as oxygen sensors, air flow meters, crankshaft position sensors, knock sensors, etc. Signal faults from these sensors can cause the engine to enter emergency operation mode, leading to weak acceleration.
