Why is the car throttle response sluggish?
1 Answers
The reasons for sluggish throttle response in a car are as follows: 1. Use of low-quality gasoline, leading to incomplete combustion. Many car owners, in order to save money, refuel at unofficial gas stations where the gasoline contains more impurities and is often mixed with water. This results in lower fuel calorific value and reduced thermal efficiency, naturally causing sluggish throttle response. Over time, this can also lead to carbon buildup, damaging the engine and reducing its lifespan. 2. The ignition system is not functioning well or accurately, causing unstable voltage output and leading to inconsistent ignition. The most common issue is with the spark plugs. For example, severe carbon buildup on the spark plugs, insufficient ignition voltage, or reaching the end of their lifespan. Depending on the situation, the spark plugs can be cleaned or replaced. 3. Clogged intake system. A clogged intake system increases the engine's intake resistance, reduces air content, and leads to incomplete fuel combustion, naturally reducing power and causing sluggish throttle response. Generally, cleaning the throttle body is the solution. 4. Fuel injection failure. For example, clogged fuel injectors or damaged injectors leading to poor fuel injection and deteriorated atomization effects.
