What Causes the Sizzling Sound When Accelerating?
3 Answers
Reasons for the sizzling sound when accelerating: 1. Engine temperature too low: When the car starts cold, the engine temperature is relatively low, and various components and fluids have not reached an optimal working environment and state. This can cause abnormal noises when accelerating. 2. Insufficient engine oil: If the engine oil is insufficient or hasn't been changed for a long time leading to oil deterioration, it will affect lubrication, causing component friction and abnormal noises. 3. Damaged drive shaft: There are many reasons why a damaged drive shaft can cause abnormal noises when accelerating, including shaft twisting, breakage, or spline tooth wear.
I've encountered a similar situation before - a buzzing sound when pressing the accelerator is often caused by throttle cable issues. It could be due to cable wear, aging, or insufficient lubrication leading to friction noise. Another common cause is air leaks in the engine compartment, such as loose intake pipe connections where high-speed airflow creates that buzzing sound. Don't overlook belt problems either - loose AC or alternator belts can produce squeaking noises. Additionally, faulty spark plugs or high-voltage wires may generate high-frequency buzzing from electrical arcing. I remember once when my older car's throttle cable lacked lubrication, adding some lubricant solved the issue. If the sound occurs frequently, I recommend prompt inspection to prevent minor issues from becoming major problems - driving safety comes first. During regular maintenance, pay attention to these components and keep the engine bay clean, as this can prevent many abnormal noises.
I recently heard a similar buzzing sound when pressing the accelerator pedal, which startled me. After checking, it might be caused by friction from the throttle pedal return spring, or a loose pulley drive belt. Many cars develop this issue after a few years, especially with significant temperature changes. A friend's car was also diagnosed with a clogged air filter causing insufficient air intake and hissing sounds. If you frequently drive at high speeds, axle wear could also produce similar noises. My personal suggestion is to start with simple checks – inspect the throttle cable position for any sticking, or clean the intake tract. If the sound persists, it's safer to get it checked at a professional shop. By the way, be cautious with cars that have modified exhaust systems – poor sealing at the connections can also cause abnormal noises.
