Why Does My Ford Focus Shake When I Accelerate?

When a Ford Focus shakes when accelerating, it is usually caused by a misalignment of the car’s parts. This misalignment can be caused by several different issues, including worn suspension system components, improper tire maintenance or alignment, or a faulty engine part. It is important to diagnose the issue correctly to ensure that the repair is effective and will not cause further damage. Common symptoms of a misaligned car are shaking or vibrating while accelerating, as well as increased fuel consumption and difficulty steering. If you experience any of these symptoms, it is recommended that you get your car checked out by a qualified mechanic as soon as possible.

Engine Issues

Your Ford Focus shaking when you accelerate could be caused by several engine issues. The first and most common is worn out spark plugs. Over time the spark plugs in your engine can become corroded or otherwise damaged, leading to misfires in the cylinders and ultimately a shaking sensation while accelerating. Another potential issue could be a faulty ignition coil, which is responsible for transferring the spark from the spark plug to the cylinder. If this coil fails, it can cause an incomplete combustion cycle which will cause a rough idle or shaking sensation while accelerating as well. Lastly, low compression in the engine could also lead to a shaking sensation when accelerating. Low compression can be caused by several issues such as worn piston rings, leaking valves, or even a worn out timing belt.

Mechanical Issues

In addition to engine problems, there are other mechanical issues that could cause your Ford Focus to shake while accelerating. Worn out motor mounts are a common culprit of this problem as they are responsible for keeping the engine firmly in place under the hood and if they fail, it can cause an excessive amount of vibration to travel through the car’s frame and into the cabin, leading to an unpleasant feeling when accelerating. Additionally, worn out or loose suspension components such as ball joints or tie rods can also lead to this type of shaking when you press on the accelerator pedal. Lastly, having incorrect tire pressure or tires that are not properly balanced can also contribute to this problem since it can create an uneven amount of force on each wheel which will cause an uncomfortable shaking sensation when you press down on the gas pedal.

Inspecting the Mechanical Components

When it comes to figuring out why your Ford Focus is shaking when accelerating, the first place you should look is the mechanical components. The most common issue is that the motor mounts may be loose or worn, which can cause shaking and vibration when accelerating. Additionally, checking for bent axles or wheels can also help identify any potential issues.

Examining the Suspension Parts and Wheels

It’s also important to examine the suspension parts and wheels of your Ford Focus. If these parts are loose or worn, they can cause a significant amount of vibration and shaking when accelerating. It’s also important to check for any bent suspension pieces, as this can cause your vehicle to shake as well.

Testing the Engine Components

Finally, it’s important to test the engine components of your Ford Focus. If any of these components are malfunctioning, it could be causing your car to shake when you accelerate. It’s important to check for possible issues with the spark plugs, fuel injectors, and other engine components that could be causing your car to shake.

FAQ & Answers

Q: Why does my Ford Focus shake when I accelerate?
A: Your Ford Focus may be shaking when you accelerate due to engine or mechanical issues. Common causes include worn spark plugs, a faulty ignition coil, low compression in the engine, worn out motor mounts, loose or worn suspension parts, and bent axles or wheels.

Q: How do I check the motor mounts on my Ford Focus?
A: To check the motor mounts of your Ford Focus, start by looking for any visible damage to the rubber insulators and metal brackets. Then examine the area around the mount to see if there is any fluid leaking from it. If everything appears to be in good condition, you can try disconnecting the battery and then starting and revving up your engine to see if there is any movement in the mount.

Q: What should I do if I have a faulty ignition coil?
A: If you suspect that you have a faulty ignition coil, it is important to have it tested by a professional mechanic. Once confirmed, they will be able to replace it with a new one so that your vehicle can run properly again.

Q: How can I tell if my suspension parts are worn or loose?
A: To determine if your suspension parts are worn or loose, start by checking for any signs of damage such as rust or corrosion on the components. Then look for any signs of wear and tear such as cracks in rubber bushings and ball joints. Finally, take your vehicle for a test drive and listen for clunking noises which could indicate loose parts.

Q: What should I do if my wheels are bent?
A: If your wheels are bent, it is important to have them replaced as soon as possible since they can cause further damage to other components of your vehicle. You should also have them inspected regularly even if they appear okay since small bends may not always be visible right away but can still affect performance.

In conclusion, the shaking of a Ford Focus when accelerating can be caused by many different problems. These include misalignments in the front suspension, worn out spark plugs or coils, worn or loose drive belts, or a failing engine mount. It is important to have a professional mechanic inspect and diagnose the issue to determine the exact cause and take corrective action.
