What Causes Occasional Unresponsiveness of the Throttle During Normal Driving?
1 Answers
The reasons for unresponsive throttle during driving are as follows: 1. Clogged fuel lines: Excessive fuel flow speed can block the pipe opening, and releasing the throttle may retract the obstruction. 2. Poor quality fuel filter: Leading to poor flow. 3. Bent fuel pipe: Insufficient fuel supply at high throttle. 4. Issues with the engine control unit (ECU): Requires diagnosis with specialized equipment at a 4S shop. 5. Poor fuel quality: Excessive water content, though this is less likely. Therefore, regular vehicle maintenance is essential to identify and address such issues. Below is an introduction to maintenance: 1. Major maintenance content: Major maintenance refers to the routine replacement of engine oil, oil filter, air filter, and fuel filter at intervals specified by the manufacturer. 2. Major maintenance intervals: Major maintenance alternates with minor maintenance. Prices vary by car brand, so follow the manufacturer's recommendations.
