Why does the Haval H6 not accelerate when stepping on the gas pedal?

[XavierLee]

Here are the reasons why the Haval H6 does not accelerate when stepping on the gas pedal: 1. Carbon deposit issue: Carbon deposits include cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, and intake carbon deposits. These areas are closely related to the engine's power output. When there is excessive carbon deposit inside the engine, the car's ignition energy decreases, intake efficiency drops, ultimately leading to reduced engine power, resulting in sluggish acceleration and muffled sounds. 2. Fuel system: Adding incompatible fuel grades can cause a decrease in the car's output power and reduced performance; or due to a blocked fuel tank cap vent, clogged fuel tank switch, fuel filter, or fuel line between the fuel tank and carburetor, the required fuel supply cannot be met, leading to a lean air-fuel mixture and weak engine acceleration. 3. Intake system: Air is one of the power sources for the engine. If the air filter is not cleaned in time after long-term use and becomes clogged, insufficient air volume will cause an overly rich air-fuel mixture, resulting in decreased engine power.
