What causes lack of power during acceleration in a Wrangler?

[SanLeah]

It indicates potential issues with the vehicle's throttle body or accelerator pedal sensor. Specific causes should be diagnosed by professionals at repair shops or 4S stores. Detailed explanations are as follows: 1. Throttle body malfunction: When the throttle body fails, symptoms may include engine shaking, unstable idle, weak acceleration, and difficulty starting when cold. In such cases, the throttle body needs thorough cleaning, especially removing accumulated carbon deposits. If structural damage occurs, immediate replacement is necessary. 2. Accelerator pedal sensor problem: Faulty pedal sensors can cause symptoms like weak acceleration, severe jerking, or unresponsiveness to throttle input. Regular inspection of the sensor is required, and using high-quality fuel is recommended. After repairs, always clear fault codes promptly to prevent electronic system memory disorders that could lead to unnecessary future complications.
