What Causes the Sizzling Sound When Pressing the Accelerator While Driving?
2 Answers
Reasons for the sizzling sound when pressing the accelerator while driving: 1. The accelerator cable is aging, and you can apply some engine oil for lubrication; 2. There is mechanical wear between the accelerator pedal components, and the same method applies—use engine oil for lubrication; 3. The vehicle's free play has increased beyond the original specifications, in which case you can visit a repair shop for adjustment; 4. If the abnormal noise comes from the clutch area, pay attention to the clutch's wear condition. Try pressing the accelerator—if the car runs normally but does not accelerate, this is a clear sign of slipping, often due to worn clutch plates. If there is a grinding or rustling sound, the clutch release bearing is likely damaged.
After driving for so many years, I often hear a hissing sound in the car when stepping on the accelerator, which is really annoying. This noise most likely comes from a few places: first, the engine belt is worn, aged, or loose, causing friction and slipping when accelerating, producing a screeching noise; second, there might be an exhaust system leak, such as a loose exhaust pipe joint or a small hole, causing a hissing sound when exhaust gas leaks; third, severe engine carbon buildup leads to knocking combustion, which sounds like an abnormal noise; fourth, aged spark plugs or ignition coil issues can cause abnormal arcing sounds. I suggest everyone not to tough it out—pull over immediately and check. First, see if the belt is loose or deformed, feel around the exhaust pipe for any leaking hot air, or use a stethoscope to pinpoint the sound's location. If you can't fix it yourself, head to a repair shop for a professional inspection right away. Ignoring it could worsen part wear, increase fuel consumption, or even cause the car to stall midway, posing serious safety risks. Remember, regular maintenance and checking the belt and exhaust system can prevent such issues and extend your car's lifespan.
