Experienced mechanics share their insights in answering this question :
On most vehicles, the engine will vibrate some at idle. Minor imbalances will cause the engine to shake some, but should not be noticeable while operating the vehicle. Major vibrations can be caused by misfires or broken engine mounts. If you feel as if the movement is abnormal, hire one of our mobile mechanics for a personal diagnosis of the shaking.

How to Identify and Fix Common car Problems ?

Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.
It is quite normal for your car engine to vibrate at optimum levels during operation. The rotation of the crankshaft, transmission gears, and other vital components inside the car engine can cause slight vibrations.
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.
Unbalanced wheels: Unbalanced wheels are one of the main causes because weight placement is vital to your BMW. If the weight is not distributed evenly, your vehicle will vibrate. If you have a lightweight suspension system, this could be the cause.
The source of the problem could be from tires that are not balanced or a worn-out spark plug. It could also be loose lug nuts. A car also vibrates for a number of reasons when you accelerate. Typically it`s from a damaged inner CV joint.
Your car shaking on idle is a pretty common occurrence, especially when you are at a stoplight waiting to drive off. Your car`s transmission gears, rotating crankshaft, as well as other inner working components, can cause vibrations that will be felt in the cabin of the vehicle.
Your car shaking while idling is another sign your car needs an oil change. Old or dirty oil thickens and does not allow the oil to do its job of lubricating the engine parts. This metal friction can create vibrating or shaking if bad enough during the ride.
While idle, the engine will complete about 10 revolutions or more per second. Because of its vast speed, the gauge displays the counts as multiples of 1,000. A vehicle that is operating normally should measure at about 1,000.
Improperly functioning spark plugs cause an uneven burn of fuel in the engine, resulting in fluctuating RPMs and a louder noise. You might also experience increased vibrations of your vehicle while sitting idle or while traveling at low speeds. These vibrations originate from the engine and can shake the entire car.
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.
If your vehicle is shaking when you are idling at a complete stop, the problem is likely to be damaged or broken motor mounts or transmission mounts. Broken motor or transmission mounts can result in severe motor shaking and should be fixed before causing other serious mechanical problems.
Often, your car shakes when idle simply because it`s time to replace your spark plugs! When yours are dirty or worn out, they fail to fire in the right way. If this happens, they`re unable to ignite the fuel located within each of the piston cylinders on time. As a result, your engine can misfire.
Motor mounts keep your engine attached to the car. Weak or broken mounts can`t hold the engine tight in the engine compartment and creates a vibration at idle. If the shaking subsides when the car is in Neutral, this could indicate the motor mounts are responsible for the vibrations.
Worn Out Brake Pads and Rotors

Over time, they become worn and your brake pads will need to be replaced. If they become too worn or unevenly worn, they aren`t making consistent and smooth contact with each other when you brake. This can cause your car to shake.

Motor mounts keep your engine attached to the car. Weak or broken mounts can`t hold the engine tight in the engine compartment and creates a vibration at idle. If the shaking subsides when the car is in Neutral, this could indicate the motor mounts are responsible for the vibrations.

engine light-p303 cylinder 3 misfire, changed spark plugs,ingition coil and cylinder valves
ANSWER : Coils and plugs are usually the starting point for a misfire code, but some basic diagnostic work might save you some money. Sometimes I like to try swapping components from cylinder to cylinder to see if the misfire moves before buying expensive parts. There are a few other problems that could lead to a P0303, like ignition primary problems, vacuum leaks, or bad injectors, but those things are usually accompanied by other codes. It’s clear that you have a dead miss. When the ECU sees a consistent misfire, it shuts off the fuel to that cylinder to prevent damage to the catalyst. The the CEL will start blinking to warn you that you may be doing damage by continuing to drive. You’re at a point where you need to have a professional do some diagnostic work. by contacting Your Mechanic, you can have a technician come to your home or office to check out your misfiring VW and recommend a fix.

BMW 318i, car is shaking. Why?
ANSWER : Hello, thanks for writing in. It sounds like you may have a serious internal engine issue, something may have come disconnected, or you have bad gas. I usually check the computer for codes first. If the computer is seeing a problem then it will be stored in a code and that will give direction to the issue. If there is nothing there then a visual inspection of the engine must be done followed by a compression test. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.

My car engine starting time with a little bit of noise sounds like it came from crankcase. What’s the best thing I can do to check?
ANSWER : Hi there. This sounds like a piston slap sound or a bearing sound. When the engine is cold, the piston skirt will be smaller than the cylinder bore and make the piston slap the cylinder wall until it get hot. The other thing could be a rod bearing that is worn making the bearing have too much clearance until the engine has met its oil pressure. Crank the engine over by hand and try to feel for a hesitation or a binding feeling, but don’t get a binding feeling and compression mixed up.

A binding feeling will have a thud and may feel like a slight tap in the turn cycle. If so, then the rod bearings need replaced or the pistons need replaced. If you need further assistance with your vehicle, then seek out a professional, such as one from YourMechanic, to help diagnose and resolve the noise on start up.

2005 cadillac cts-v and is a flooded car and wont start but does turn, i want to know how i can save the engine is a ls6 5.7
ANSWER : Hi there. Usually when an engine is flooded with water, the only way to rebuild it correctly is to pull out of the vehicle, completely disassemble, fully clean (including sandblasting any excessive rust off cylinder heads, blocks and intake) and rebuilding from scratch.

car shakes when idle and accelerating
ANSWER : It is very possible that you have a valve cover gasket or spark plug tube seal leak on your vehicle. These type of leaks will allow oil to leak onto the spark plugs causing misfires. When the engine misfires due to oil getting on the spark plug, the engine oil will burn. Since oil and tires are both petroleum products, they will both smell similar when they are burning. I would recommend having an oil leak inspection performed by a qualified professional to determine if there is an oil leak. Consider YourMechanic as an Oil/Fluid leak inspection can be peformed at your home or office.

The VSA (!) light is on, engine light flashing, and it feels like the motor or car is shaking.
ANSWER : Hello, thank you for writing in. The VSA (vehicle stability control) warning light is telling you there is an issue detected with the system. The vehicle should be driven as minimally as possible. The issue may be directly related to the VSA system, or it may be related to one of the input sensors. The easiest way to help determine the problem is to scan the vehicle for diagnostic codes. They will point you in the right direction. Your owner’s manual will also have more information about the system. For more diagnostic help, contact our service department.

Was driving on the expressway and my car started shaking, check engine light turned on, oil light turned on and off
ANSWER : Hello, thank you for writing in. Shaking and vibrating typically comes from a misfire, or poor engine performance. A lack of oil will absolutely contribute to these symptoms and amplify them, if not cause them to begin with. You want to turn your attention to the cause of the oil leak. If external (you can see the leaking oil), then you will want to trace the leak to the component which has failed. If the leak is internal (or the engine is consuming oil), the leak will be harder to find. It will also explain the poor engine performance due to excess oil in the combustion chamber. A head gasket is one of the main components that will fail and cause these issues. It is however not common for a vehicle this age to have these kinds of problems. You will also want to scan the computer, and see what codes are triggering your check engine light. These diagnostic tools will help you determine what system(s) is to blame for the malfunction.
