The most frequent causes of shaking when your automobile is stopped or idle are old spark plugs or vacuum leaks. It may also be brought on by faulty gasoline pumps, worn serpentine belts, loose or damaged engine mounts, or any other fuel-related problems.
When your automobile shakes or vibrates at idle, you should use an OBD-II scanner to check the fault codes. Below are some potential causes if you can’t locate any trouble codes or just aren’t sure what they mean:
The seven most frequent causes of car vibrations at idle or while stopped are listed in further detail below.

soiled or exhausted The Most Common Cause of Engine Shaking Is Spark Plugs
When spark plugs are unclean or worn out, they won’t fire properly, which means the fuel in each of the piston cylinders isn’t ignited promptly. As a result, the engine misfires, also referred to as “not firing on all cylinders.” Spark plugs that are dirty can occasionally be cleaned, but because they are typically inexpensive, it is best to just replace them. They can be carefully installed and calibrated with the help of a skilled mechanic.
Spiking Plugs
Even though automakers brag that current engines allow you to wait 100,000 miles before changing your spark plugs, this isn’t always the case. Your car will tremble when you’re stopped if your spark plugs are filthy or worn. Because they can’t effectively ignite the fuel in the piston cylinder, dirty or worn plugs cause misfires. Thankfully, replacement plugs don’t cost a lot of money.
Why does a BMW tremble?
worn-out rotors and brake pads Your brake pads will eventually need to be replaced because they become worn over time. When you brake, they don’t make constant and smooth contact with each other if they are too worn or worn unevenly. Your automobile may tremble as a result of this.
Why does my BMW tremble while it is parked?
The engine is kept affixed to the vehicle using motor mounts. When parked with the engine running or at a stoplight, if the car shakes or the engine trembles a lot, it could be a sign that the motor mounts or gearbox mounts are cracked or damaged. Put the car in neutral to check if this is the genuine issue. If the shaking stops, it’s a clear sign that the engine’s motor mounts require a mechanic’s inspection.
What causes my car to tremble while I’m stopped?
Motor mounts or transmission mounts that are broken or damaged are likely to be the cause of your car shaking while it is stationary. Before generating additional severe mechanical issues, broken motor or gearbox mounts can cause extreme motor shaking.
Why does my BMW shake while it is idle?
Your engine is kept connected to the vehicle via motor mounts. At idle, a vibration is produced by weak or damaged mounts that are unable to keep the engine securely in the engine compartment. If the shaking stops when the vehicle is in neutral, the vibrations may be coming from the motor mounts.
Why does my car shake while it is idle?
You shouldn’t disregard a rough idle because it could be a sign of a significant underlying issue with your car. Take your car to a qualified mechanic, like the ones at our Honda dealership, for diagnostic and repair if it rattles when it is idling.
These are a some of the frequent causes of rough idle:
- Motor mounts: The motor and gearbox mounts’ function is to reduce vibration. You will experience considerable vibration when they break, especially at idle. Put your automobile in neutral and check this for yourself. If the shaking stops, your mounts may very well be broken. A qualified mechanic can confirm this in a flash.
- Timing belt: The timing belt coordinates the movements of a number of parts and accessories. Uneven time from a stretched, ripped, or worn-out belt results in shaking. High-mileage automobiles are most likely to experience this. Any belts that exhibit fractures, ribbing, or looseness should be changed straight soon.
- Fuel intake: Engines dislike dirt, particularly the fuel injectors and intake valves in particular. They will provide inconsistent amounts of gasoline with each engine cycle if they get clogged with dirt or debris, which will result in a high-frequency shutter or tremor. By using high-quality fuel and maybe additives that clean the fuel intake system, you can frequently avoid the issue in addition to having a specialist remove the debris.
- Spark plugs: Faulty, misfiring, or worn-out spark plugs can cause vibration. If changing the plugs doesn’t resolve the issue, you can have more serious compression-related problems. Use the plugs that the automaker recommends if you need to replace any. Cheap plugs are a waste of money.
- Hoses: Broken, slack, or disconnected hoses are frequently to blame for engine tremor. Poor air/vacuum hoses might result in major problems. Hoses can be repaired or replaced as necessary.
Choose the services of a factory-authorized service facility, such as the one at our Honda dealership, unless you are a skilled shade-tree technician. Your automobile will be carefully maintained and serviced by our licensed specialists, getting you back on the road as soon as possible.

Because of the rotation of the crankshaft, transmission gears, and other moving parts in your engine, it’s typical for your automobile to vibrate somewhat when you’re driving. The moment has come to look into why these slight vibrations start to seem more like shaking.
Why does my car shake when it is at rest but not when I’m driving?
Something as basic as poor motor mounts can be the cause of trembling when idling that smooths out while driving. Additionally, it can be an indication of clogged spark plugs, damaged hoses and belts, or a broken idle speed control system. Finally, check the fuel intake system to determine if it is the issue.
Is it a cause for concern if my automobile trembles?
The issue may be caused by the tires and can be solved in a number of ways depending on the type of vibration the driver is experiencing. The tires may need to be balanced if vibration is experienced at a particular speed. The driver could require a tire rotation if the tires are wearing unevenly and making the vehicle vibrate. In some circumstances, the driver may require new tires to address the vibration issue.
Regardless of the source, drivers may avoid this issue by coming to our Kia dealership in St. Petersburg and having trained, licensed personnel evaluate and examine your car. They will provide you with a detailed maintenance schedule tailored to the make and model of your car, which should help you avoid future issues like vibration.
What are the five potential reasons why a car might shake?
Pay close attention to the suspension system if the steering wheel is the primary source of shaking. This shouldn’t be treated as a “wait and see” situation because it might result in a major issue. The tie rods, shock absorbers, struts, bearings, and ball joints are a few potential culprits.
This needs to be examined right away because it needs a professional’s help.
Can an automobile be harmed by shaking?
You shouldn’t rule it out because a small accident could be the culprit. When you find that your automobile is shaking, regardless of whether it is new or used, it is time to have it serviced or repaired. Your car’s mileage will suffer and its components will experience more wear and tear if it is shaken.
Will alignment cause the car to sway?
While a shaking steering wheel is a typical indicator of alignment concerns, similar automotive problems also carry the following telling signs:
- Continual Vibration: No matter whether you are braking, accelerating, or maintaining a constant speed, alignment problems will result in continuous vehicle vibration.
- The steering wheel may also appear to be “pushing” your car in one direction or the other rather than smoothly navigating a straight line.
- Whirling noises and other tire noises may be indicators of alignment problems.
- Uneven Tire Wear: Because the alignment problems may result in excessively high road friction, you may start to observe uneven tire wear. Consider the possibility that only one of your tires is worn out while the others appear to be in good condition. In some instances, the tread on one side of a tire may be heavy and still have substantial wear on the other.
Your tires are more likely to become out of alignment the longer you drive, especially in locations with unreliable, uneven roads. Due to their frequent alignment checks and services, delivery drivers, Uber drivers, Lyft drivers, and drivers that commute a long distance all find themselves in this situation.
What results in front end trembling?
Out of Balance Tires The steering wheel shaking that you might encounter has this as its most visible and frequent cause. Your car’s steering wheel and suspension may tremble if your tires are out of balance or out of alignment.
Can faulty spark plugs create a shaken car?
Your spark plugs may be to blame if you see that your engine is unusually noisy while stopped at a stoplight or stop sign. Inefficiently working spark plugs result in an uneven fuel burn in the engine, causing the RPMs to fluctuate and the noise to get louder.
Additionally, while idling or moving at a slow speed, your vehicle may vibrate more intensely. The entire car may shake as a result of these vibrations, which come from the engine.
Can alignment eliminate shaking?
The poor alignment of the wheels is another frequent reason for steering wheel vibration. By ensuring that all wheels are pointed in the same direction, a wheel alignment will typically eliminate the shaking. Examining the tread of the tire is one of the quickest ways to identify misalignment. Tires on a misaligned vehicle frequently experience uneven tread wear, with the inside tread being significantly more worn than the exterior. The car is probably out of alignment if the steering wheel is straight and in the middle yet it still pulls to one side.
Wheel alignment is done via the suspension system, therefore it will likely be impacted if there are any suspension problems, such as damage from normal wear, driving on bad roads, or an accident. After a vehicle’s suspension has been raised or lowered, or if a vehicle has had any new steering and suspension elements added, an alignment is also required before any prolonged driving.
