Sudden loss of power when accelerating may be caused by fuel pump issues. Below are common reasons for sudden power loss when pressing the accelerator: 1. Acceleration sensor malfunction. Examples: sensor damage (open/short circuit). 2. Throttle body failure. Examples: excessive dirt or sticking. 3. Spark plug ignition failure. Examples: poor ignition or misfiring, resulting in unresponsive acceleration. 4. Certain switch-type electrical components. Examples: model-specific connected parts like brake switch (signal), requiring model-specific inspection. 5. Throttle position sensor failure. Examples: damaged position sensor or signal loss due to wiring issues. 6. Ignition system failures (distributor, ignition coil, high-voltage wires, etc.). Examples: leakage, aging, or quality issues in these components causing poor ignition and unresponsive acceleration.

What causes the car tire warning light to come on?

This situation is usually caused by very slow air leakage. At this time, you can use a tire pressure gauge to measure the pressure. The front tires should be 2.3 bar, and the rear tires should be 2.5 bar. If there is insufficient air, you should replenish it. According to the international GBT2978-2008 standard, the required inflation pressure for standard car tires is 2.4-2.5 bar. If the tire pressure of a certain tire is too low, high-speed operation will cause the tire temperature to rise, which in turn will cause the tire pressure to increase. In this case, you should stop and rest in time or replace the spare tire.
