When I let off the gas my car makes a noise?
It can be an indication of an extremely worn bushing. Do not ignore a car that thuds when taking the foot off the accelerator pedal. Have an auto mechanic perform a vehicle inspection to determine why your car makes a knocking sound when letting off the gas pedal.
Why does my engine rattle when I let off the gas?
Sometimes the rattling sound during acceleration is caused by a loose bracket on the exhaust system or another mechanical component. The issue could also be a small exhaust manifold leak or something entirely different.
Why does my car make a whining sound when I Turn on the accelerator?
When I turn the car with foot on accelerator, no whining sound. Its best you get a proper mechanic to look at it. We are just guessing here as we have limited information to properly give details.

Can timing belt caused this as when pedal is on (no engine brake), noise disappears. The whining noise happens on all gears. (Tyres are new and definitely not typre noise). I encountered this problem with my old sub legacy. Whining sound when idling, but sound gone when i accelerate.
Why does my mech make a whining sound when idling?
Whining sound when idling, but sound gone when i accelerate. Can’t remember whether my mech say is timing belt or alternator belt. But its definitely one of these two.
Why does my car Rattle at high speeds?
These components act as a thermo-reflective barrier between the exhaust system and other parts including gas tank, fuel lines, and the cabin of a car. When they are loose or broken, they fail to completely block the heat transfer to these key areas. As a result, you will hear frightening rattles at higher speeds.
Why does my car make a noise when I accelerate?
Belt noise can mean the belt is worn or loose. Belt noise can also come when one of the pulleys the belt is riding on starts to fail. When the belt no longer moves smoothly along the pulleys, it makes a noise when the car is accelerating. The other noise you might be accustomed to is that of a loud exhaust system.
Why do I hear a low pitched hum while driving?
While driving, you hear a low-pitched hum. As you accelerate, the noise gets louder—maybe it sounds like an airplane taking off—but after a certain speed the volume is consistent. When you make a turn, the noise gets louder; but if you turn the other way, it disappears. What it could mean: This is most likely a wheel bearing noise.
What causes a low pitch noise when accelerating?
Noise:Howling while accelerating over a small speed range (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading Noise:Howling after gear set installation Cause:Faulty gears or improper installation Noise:Low-pitch rumble at all speeds over 20 miles per hour Cause:Worn carrier bearings
Why does my car shake when I accelerate?
During acceleration, the motor mounts the engine vibrates naturally as RPM’s increase. Engine mounts are the component responsible for securing the engine of a vehicle to the chassis. They come in a variety of shapes and sizes to fit a wide variety of needs, but they all serve the same purpose of mounting the engine and dampening engine vibration.
Why does my car make a rattling noise when I let off the gas?
Take your foot off the throttle and the flow is suddenly cut off even though the engine is still turning and the valves are still opening and closing. That creates vibrations in the air column within the exhaust pipe, which can rattle anything slightly loose–like a heat shield. I may be way off base, but that’s how I picture it!
Is it okay to run a 1968 beetle on unleaded gas?
Short answer: yes. If you’re getting a weird knocking or banging noise, read the section below Long answer: I’ve seen this argued about a lot on forums and mailing lists. People who know a lot more about cars and engineering convinced me it was fine and I’ve been running my 1968 Beetle on unleaded petrol (gas) for several years now.
Why does my car make a noise when I open the window?
Whether you call it wind throb or buffeting or just plain annoying, it happens when someone in the car opens a single window at speed and it stops when a second window rolls down. The phenomenon that produces this noise is the Helmholtz Resonance, the same principle that makes a bottle hum when you blow over its open top.
Why does my car make a noise when I release the clutch?
Next release the clutch with the transmission in first gear. Noise under this condition indicates a worn release bearing or a worn pilot bearing. To isolate the two, keep the clutch pedal on the floor and shift the transmission into neutral. If the noise persists, the release bearing is bad. If the noise is gone, the pilot bearing is bad.
