Why Does the Car Throttle Response Become Slower?
2 Answers
Reasons for slower car throttle response: 1. Factory electronic throttle tuning issues causing response lag, feeling a step behind; 2. CVT transmission causing throttle response lag, feeling a step behind; 3. Insufficient engine torque, feeling a step behind, turbo suddenly kicks in, torque increases and power rises; 4. Dirty electronic throttle body, fuel injectors, etc.; 5. ECO mode for fuel saving can also cause throttle response lag; 6. Poor driving habits, always operating at ultra-low RPM, the computer learns the driving habits; 7. Poor driving habits, always driving in high gear at low RPM, causing insufficient torque for rapid acceleration, unable to accelerate.
My throttle response has become sluggish, which worries me a bit. Recently, when driving, I feel that after pressing the accelerator, the engine lacks power and responds slowly. I recalled my daily driving habits and thought it might be caused by engine issues. For example, excessive carbon buildup in the throttle body can clog the intake passage, making the throttle response sluggish; or aging spark plugs can cause poor ignition, preventing the fuel from burning completely. Also, a dirty air filter can obstruct airflow, affecting power output. I suggest checking these simple parts first. If it's a carbon buildup issue, you can try cleaning the throttle body yourself. Long-term neglect may lead to increased fuel consumption or even engine damage, so timely action is important. Safety is also a concern, as delayed acceleration in traffic may increase the risk of rear-end collisions. In such cases, it's best to reduce high-speed driving.
