What causes the Chevrolet Cruze to shake and have weak acceleration?

[StephenDella]

The reasons for the Chevrolet Cruze shaking and having weak acceleration are as follows: 1. Carbon deposits: Carbon deposits include cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, and intake carbon deposits. These areas are directly related to the engine's power output. When there is excessive carbon buildup inside the engine, the car's ignition energy decreases, intake efficiency drops, and ultimately, the engine's power is reduced, resulting in shaking and weak acceleration. 2. Fuel system: Adding an incompatible fuel grade can cause the car's output power to decrease and reduce performance. Alternatively, if the fuel tank cap vent is blocked, it may not meet the required fuel supply, leading to a lean air-fuel mixture and weak engine acceleration.
