Hello – I would be suspicious of an exhaust system hanger which has gone weak, and is allowing the exhaust to bump into the chassis at an idle. It is also possible that the fuel pump is wearing out, and the "chattering" that a worn fuel pump makes is transmitted through the fuel tank into the car. It would be easier to notice at a stoplight, but fades while driving as other road noise increases. I recommend a vibration and noise inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

Motor mounts keep the engine attached to the car. If the vehicle shakes or the engine shudders a lot when stopped at a stoplight, or when parked with the engine idling, it might indicate the motor mounts or transmission mounts are damaged or broken. To see if this is really the problem, shift the car into neutral.
It`s normal for your car to vibrate slightly when you`re driving thanks to the rotation of the crankshaft, transmission gears and other moving parts in your engine.
If vibration is felt at certain speeds, the tires may need to be balanced. If the tires are wearing unevenly and causing the car to vibrate, the driver may need a tire rotation. In some cases, the driver may need new tires to solve the problem of vibration.
Setting matter in motion like this obviously requires energy, which will inevitably become dissipated as the waves pass through the air and more solid materials. Eventually the motion ceases entirely and no more sound can be heard – producing silence.
Buzzing Sensations, like a sudden vibrating, electric zap, or tremor feeling anywhere on or in the body is a common anxiety disorder symptom, including anxiety and panic attacks, generalized anxiety disorder, social anxiety disorder, obsessive-compulsive disorder, phobias, and others.
Motor mounts: It`s the job of the motor and transmission mounts to dampen vibration. When they break, you`ll feel excessive vibration, especially at idle. You can diagnose this yourself by putting your car in neutral. If the shaking lessens, you very well could have broken mounts.
Consistent Shaking: Alignment issues will cause constant vehicle vibration, no matter whether you are braking, accelerating, or maintaining a consistent speed. Steering Wheel Pulling: You may also notice that your vehicle is “pulling” towards one side of the road or another rather than seamlessly steering straight.
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
Low automatic transmission fluid can cause shaking. If the shaking is accompanied by the check engine light, it`s time to visit a mechanic. Drivers of manual cars might discover their clutch master cylinder is the source of the shaking.
A loose or disconnected air hose or vacuum hose can cause quite a bit of violent shaking and vibration in your car`s engine. To correct the problem, simply look for any loose or disconnected hoses and reattach them and replace them as needed.
Rough, bumpy rides can be due to bad tire alignment, incorrect air pressure – too low, too high, different pressures in each tire – or even the tires not being mounted properly. Worst case scenario could be the rims themselves have become damaged or warped.
Vibration can be caused by one or more factors at any given time, the most common being imbalance, misalignment, wear and looseness. Imbalance – A “heavy spot” in a rotating component will cause vibration when the unbalanced weight rotates around the machine`s axis, creating a centrifugal force.
A person may experience internal tremors in the trunk, arms, legs, or internal organs. Internal tremors are not harmful, but they be can be worrying and may interfere with a person`s daily life.
Whole-body vibration can cause fatigue, stomach problems, headache, loss of balance and “shakiness” shortly after or during exposure. The symptoms are similar to those that many people experience after a long car or boat trip.
Pallesthesia (\ˌpal-es-ˈthē-zh(ē-)ə\), or vibratory sensation, is the ability to perceive vibration. This sensation, often conducted through skin and bone, is usually generated by mechanoreceptors such as Pacinian corpuscles, Merkel disk receptors, and tactile corpuscles.
Causes of a rough idle. Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.
Tire Problems
Tires are one of the most common causes of car vibrations. One of the possible issues are out-of-balance tires. Your problems may not be noticeable at slow speeds, but the shaking will intensify as you accelerate to 55-60 miles per hour. The steering wheel, or even the entire car, will start to vibrate.
The recommended length on how long you should stay on a vibration machine is 15 to 30 minutes at a time on 3 to 4 occasions each week.
If your wheels are misaligned, your car will usually “drift” when you take your hands off the wheel, and the steering wheel itself may vibrate or shake. This is a pretty easy fix – just take your car in for an alignment, and the problem will be resolved.
Bad wheel bearings can cause the steering wheel to vibrate. The intensity increases as the vehicle speed increases and the vehicle turns to the left or right. However, the vibration could be linked to an out-of-round tire (there could be a flat spot on the tire) or a tire that is no longer balanced.
Vibrations caused by out-of-round tires or wheels, bent rims or excessive hub runout can be diagnosed on the vehicle with a dial indicator, or on a wheel balancer that has this capability.
The gearbox fluid acts as a lubricant, so if you sense vibrations in the shifter when changing gears, then a gearbox oil change may be needed.
Difficulty Shifting Gears – If you ever accelerate and hear your engine rev, but don`t feel your car go any faster, your transmission is likely stuck in gear. Drivers with a manual transmission will feel some resistance when you try to shift. Not being able to shift is a direct result of having low transmission fluid.
