Why does the Buick Verano feel sluggish and weak when accelerating?

[MacRyder]

Here are the reasons why the Buick Verano feels sluggish and weak when accelerating: 1. Carbon buildup issue: This includes carbon deposits in the cylinders, throttle body, spark plugs, and intake system. 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, ultimately leading to reduced engine power, resulting in sluggish acceleration and a muffled sound. 2. Engine overheating: Insufficient engine oil, low engine coolant, or malfunctioning engine cooling systems can increase the engine's load, leading to poor heat dissipation. Engine overheating can cause poor lubrication, increased mechanical wear, reduced engine power, and result in weak acceleration.
