What Causes the Malibu to Feel Sluggish and Lack Power During Acceleration?

[LenaMarie]

The reasons for the Malibu feeling sluggish and lacking power during acceleration are as follows: 1. Throttle body malfunction: When the throttle body malfunctions, the vehicle may exhibit symptoms such as engine shaking, unstable idling, weak acceleration, and difficulty starting when cold. In this case, the throttle body should be thoroughly cleaned, especially removing any oil sludge attached to it. If the throttle body is structurally damaged, it should be replaced promptly. 2. Throttle position sensor issues: When the throttle pedal malfunctions, the vehicle may show symptoms like weak acceleration, severe jerking, and unresponsiveness to throttle input. In such cases, the throttle position sensor should be inspected, and it's advisable to use high-quality fuel regularly. After repairs, the fault codes should be cleared promptly to prevent memory confusion in the vehicle's electronic system, which could cause unnecessary issues later.
