What Are the Reasons for Delayed Throttle Response in Cars?
2 Answers
Car throttle response delay is caused by: 1. Fuel quality issues: Using low-quality gasoline can lead to incomplete combustion in the engine, easily forming carbon deposits. Low fuel calorific value and reduced thermal efficiency also contribute; 2. Blocked intake and exhaust systems: This causes poor engine breathing, resulting in increased intake resistance, reduced oxygen content, and incomplete fuel combustion, leading to significantly decreased power. When experiencing throttle response delay, it is recommended to perform routine maintenance (such as cleaning the fuel system, fuel injectors, spark plugs, and replacing the fuel filter, air filter, and oil filter) to see if the condition improves. If there is no noticeable change, then consider replacing components.
I once experienced a situation where pressing the accelerator pedal had no response, and the car felt like it was being dragged, especially when overtaking, which was very dangerous. Common causes could be a clogged air filter with too much dirt affecting the engine's air intake efficiency. There might also be issues with the fuel system, such as a dirty fuel filter, a faulty pump, or clogged fuel injectors, which prevent fuel from entering, leading to insufficient power and a sluggish feeling. The ignition system is also crucial; old spark plugs can cause slow ignition, making the engine fail to ignite the fuel properly. It's recommended to first check the air filter yourself—if it's dirty, replace it with a new one, as it's cheap and simple. Regular maintenance can prevent such embarrassing situations. I check every 5,000 kilometers, which has reduced a lot of trouble.
