Engine Feels Sluggish and Lacks Acceleration Power?

[Giselle]

The causes and solutions for an engine feeling sluggish and lacking acceleration power are as follows: 1. Ignition system issues. For example, spark plugs have reached their lifespan limit, excessive gap between spark plug electrodes, severe leakage in individual spark plugs, or heavy carbon buildup on spark plugs. Solution: Replace the spark plugs. 2. Intake system problems. Leading to an overly rich or lean air-fuel mixture, such as throttle body blockage, abnormal throttle opening, or carbon buildup in the throttle body. Solution: First, clean the throttle body to see if it resolves the issue. If the problem persists, replace the throttle body. 3. Fuel system issues. First, consider whether the fuel injectors are problematic, such as poor fuel atomization or severe carbon buildup in the injectors. Solution: Clean or replace the fuel injectors.
