Damaged Or Clogged Fuel Intake/fuel Pump/fuel Injectors/filter

Car Shakes When Accelerating

If anything is going on with your fuel system, youll likely have a vibrating or shaking engine. Thats because if one of the engines cylinders isnt getting enough fuel, it will throw the entire balance of the engine off.

But even if youve identified it as a problem with your fuel system, there are a couple of different potential culprits. The first place to check should be your fuel filter. If your fuel filter is clogged, nothing will work the way it should, and it can even end up damaging other components.

From there, you should look into your fuel injectors, fuel intake, or fuel pump. Many of these issues will cause a check engine light, which can help you narrow down the problem.

Misaligned And Worn Out Belts

Misaligned or worn-out Serpentine belts can cause vibrations while your vehicle is idling.

Typically if your serpentine belt is misaligned, the belt will make a screeching or a chirping sound due to the loose-fitting belt slipping on the underdrive pulleys.

A worn-out belt or a misaligned belt connected to your engine or other components could be the reason why your vehicle shakes while idling.

The serpentine belt powers your AC compressor, water pump, power steering, and your alternator. If your belts are worn out or loose-fitting on the underdrive pulleys, you could experience shaking or vibrations inside your vehicle.

Your vehicle is working harder to stay running while idling.

Inspect your vehicle belts by looking for cracks, rips and also check for tight tension.

If you see damage or excessive wear on your belts, we recommend that you replace your belts. Belts are inexpensive and easily accessible.;;

Reasons Your Car Is Vibrating When Idle Or Stopped

Your vehicles dashboard is how your car communicates to you. It tells you when fuel is low, the speed youre traveling, and even reminds you to put on your seatbelt. Theres another gauge on the dashboard that few of us notice, however, its there for a good reason.

Its the RPM gauge, also known as the tachometer, that measures the rate of revolutions per minute produced by the engine.;

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.

When a vehicles RPMs fall below or are increasingly higher than normal, especially if the car vibrates when idle, something is not right.

What Does It Mean By Car Shaking When Stopped Or Idle

When you sit inside your car and just start the engine, and dont do anything else, like hit the gas, putting into gear or acceleration, your car is in idle.

When your car is in idle, it is perfectly normal for it to vibrate a little.

This is because of the essential parts of the engine that have to move when the engine starts, like timing belts and gears.

A smoothly idling engine is supposed to provide the parts with enough power for them to be able to operate steadily.

It also enables the basic systems of the car to run, like the electrical systems, the power steering or the cooling systems.

However, if it is vibrating more than normal, it means that it is about time you give your car a thorough inspection.

When your car is struggling to maintain a steady vibrational pattern when it is at idle, it is an indicator that you need to take a look at all the causes and fixes.

Dirty Or Fatigued Spark Plugs

7 Causes of Car Shakes When Idle, Accelerating, Driving ...

Spark plugs may be small, but their impact on your cars performance is substantial. Properly functioning spark plugs deliver electricity from the ignition system to the combustion chamber. This puts the pistons in motion and allows your car to start and operate as intended.

Dirty or fatigued spark plugs wont fire evenly, which causes the pistons to misfire and your car to shudder or shake while idling and driving. You may be able to clean dirty spark plugs as a quick fix. However, youre usually better off replacing them, as theyre inexpensive and a certified auto technician at Honda of Seattle can replace them with ease.

What To Do If Car Shakes When Idle Or Driving At Slow Speeds

How your car feels when you start the engine and begin driving is important. This is the time when you are most likely to notice unusual sounds or vibrations. All car engines vibrate to some degree, but it should be smooth. If your cars idle RPMs are erratic or the car shakes when you are driving it needs some attention. If you ignore unusual car vibrations, it can lead to worse problems down the line.

A car engine needs the right mixture of spark, fuel and compression to give you a smooth ride. Many systems work together to create this precise blend of elements. If one of these systems fails your car will vibrate or shake, so this is a good place to start troubleshooting.

The most common reasons for a car to shake when idling or stopped are as follows:

  • Bad radiator fan
  • Failing idle control valve

If your car does not start shaking until you begin driving, your problem may be in the tires or brakes:

  • Warped brake rotors
  • Worn brake pads
  • Imbalanced Tires

Sometimes your car may vibrate when at idle and stop when you reach higher speeds. Some issues that can cause this are:

  • Cold temperatures
  • Transmission problems
  • Dirty throttle body

The number of parts that can cause your car to shake may seem overwhelming. If your check engine light is on, ask your local auto parts store to read the code. This will help narrow down which area of the car may be causing your trouble.

Top 5 Reasons Your Car is Shaking or Vibrating – Symptoms and Fixes Included

We’ve discussed your car shaking while braking, but what if your car shakes when your foot is nowhere near the brake pedal? If this sounds like your situation, you may have misaligned wheels or improperly balanced tires. Typically, you can tell which of the two issues is to blame depending on where you feel the shaking. If the shakes come from the steering wheel, your car likely needs an alignment check and service. If they come from the floorboards and seats, a tire balance may be needed.

While wheel misalignment happens when suspension components are not properly angled, tire imbalance occurs when the weight of your car isnt properly distributed on all four tires. Such improper weight distribution can lead to excessive shaking, especially when you drive above 55 mph. To make matters worse, imbalanced tires can wear out prematurely, creating dangerous driving conditions that can only be remedied with entirely new tires.

Why Is My Check Engine Light On While My Car Is Shaking

Your check engine light might come while your car is shaking for a host of reasons. The first reason that it might be on is due to the oxygen sensor providing a trouble code. These sensors are designed to measure the ratio of unburned oxygen to fuel, in order to see if the ratio is providing an optimal working capacity.

If the oxygen sensors are malfunctioning and sending data that doesn’t make sense, your fuel efficiency can be reduced sometimes by up to a whopping 40%. Your car will often time stall, hesitate while trying to accelerate, or have a rough and shaky idle.

Oxygen sensors typically fail due to an accumulation of residue. This occurs because of oil leaks in the engine, a fuel mixture that is incorrectly balanced, or coolants have left behind deposits that interfere with the sensor accuracy. You will need to replace your oxygen sensor to turn the check engine light off and prevent your car from having a rough idle.

What Should I Do When My Check Engine Light Is Flashing

You have a number of options. You can take your car to your local dealership, and have them do a full diagnosis. Usually, dealerships have extensive knowledge of vehicles. For example, Chevy Cobalt know their cars very well; so, that is a great option.

There are also many independent shops that specialize in different brands, maybe the brand of your car including Acura, Chevy, Dodge, Ford, Honda, Hummer, Jeep, Nissan, Subaru, Toyota, GMC etc.. You can even take your car to such shops for a full diagnosis. The third option that you can settle for is buying your own OBD-II scanner and conduct a DIY.

With each of these options come some advantages and disadvantages. If you take your car to a dealership or an independent shop, odds are you are going to be charged a diagnostic fee. The good thing is that they will have all the info and equipment needed for proper diagnosis.

Using your own OBD-II scanner, you may save money in the diagnostic process. However, you might not have all the repair and all the diagnostic information. You may also lack the test equipment for properly pinpointing the problem with your car.

Why Does My Car Shake When At Idle

Rough idle is a symptom of a problem within your vehicle that you shouldnt ignore, as it may indicate a serious underlying issue. If your car shakes at idle, take it to a certified mechanic, like the ones at our Honda dealership, for diagnosis and correction.

Here are some of the common reasons for rough idle:

  • Motor mounts: Its the job of the motor and transmission mounts to dampen vibration. When they break, youll 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. A professional mechanic can quickly confirm this.
  • Timing belt: The timing belt choreographs the actions of several components and accessories. A stretched, torn or worn-out belt will result in inconsistent timing, which causes shaking. This most often occurs in high-mileage vehicles. If you start seeing cracks, ribbing or looseness in any of your belts, have them replaced right away.
  • Fuel intake: Engines dont like dirt, and thats especially true of the fuel injectors and intake valves. If they become befouled by dirt or debris, they will deliver uneven amounts of fuel with each engine cycle, causing a high-frequency shutter or shake. A technician can clean out the dirt, and you can often avoid the problem by using quality fuel and perhaps additives that clean the fuel intake system.

    Damaged Driveshaft Or Propshaft

    A driveshaft/ prop shaft that isnt perfectly inline can cause a bad shaking sensation through the vehicle when driving and progressively worsen as your vehicles speed increases.;

    If you have a front-wheel drive, it can be a faulty drive shaft that goes out to each front wheel. If you have a rear-wheel drive, it can either be the two driveshafts going out the CV joint or the big prop shaft going from the gearbox to the differential. When there is an unbalance in the prop shaft, you can usually feel small vibrations while not accelerating also.

    If you have a four wheel it can by any of the axles mentioned above.

    Driving your vehicle on a ramp with all 4 wheels lifted off the floor is the best way to determine if your driveshaft/ prop shaft is damaged. As the vehicle is driven on the ramp, visually inspect to ensure that all of the shafts rotate around a constant fixed point. If any damaged shafts are found, they will need replacing before they cause further damage to your CV joints and other drivetrain components.;
