Why does the throttle suddenly fail to accelerate while driving?
1 Answers
If the vehicle suddenly fails to accelerate during normal driving, it may be caused by excessive carbon deposits. Due to carbon buildup, localized high temperatures can cause the combustible mixture to ignite prematurely before the spark plug fires, a phenomenon commonly known as detonation. This disrupts the normal operation of the engine, causing not only vibrations but also a lack of power when stepping on the accelerator, making the vehicle feel sluggish. Below are the steps to address sudden loss of acceleration in a car: 1. Check the fuel tank pump to see if it is functioning properly. The fuel pump motor should produce a sound. If the fuel pump fails to supply fuel normally, it can lead to insufficient vehicle power. 2. Inspect the fuel filter to ensure it is working well and check for leaks or blockages. If the leak is severe, starting the vehicle could potentially ignite it due to static electricity. 3. Examine the intake pipe for any debris blockages. Remove the air filter to check for water ingress, and replace the air filter if necessary. 4. Verify the correctness of the valve timing and ensure the intake and exhaust pipes are tightly sealed. You can clean the throttle body or add a cleaning-type fuel additive (fuel system cleaner) to the fuel, which can help remove some carbon deposits.
