Engine Shaking When Accelerating [Causes & Solution]

Have you ever been driving your car and suddenly felt like it was about to shake apart? Are you worried that something may be wrong with your engine when the shaking starts up every time you accelerate? If so, then this article is for you!
We’ll explore some of the common causes behind engine shaking when accelerating – from worn out spark plugs to faulty fuel injectors – and offer helpful tips on how to diagnose and solve the problem.

So stay tuned, as we delve deep into all things related to a shuddering motor!

Engine Shaking When Accelerating – Troubleshoot And Diagnosis

Engine Shaking When Accelerating

When the car engine starts shaking and vibrating during acceleration, it can be a sign of an underlying issue. This shaking can cause further damage to the engine if not taken care of immediately.

With that being said, there are several reasons why an engine may shake when accelerating.

Below, we will discuss the most common causes for engine shaking when accelerating and how to diagnose and fix them.

1. Ignition Coils

Ignition coils are essential components in the vehicle’s engine and work to transform battery voltage into thousands of volts for spark plug ignition. When an ignition coil fails, it won’t generate enough sparks to ignite all cylinders, resulting in engine shaking.

This type of shaking will occur during acceleration, or when the driver attempts to take their foot off the gas pedal and coast down a hill. Ignition coils may fail due to age and wear-and-tear, but some external factors such as extreme cold or heat might also contribute to their failure.

In order to diagnose whether an ignition coil is causing engine vibration or not, mechanics should first check for any misfires in each cylinder using a diagnostic scan tool.

The first sign of an ignition coil going bad is usually engine misfires which feel like jerks or stutters in the car’s power as you accelerate. As time goes on, these misfires can lead to other symptoms such as a rough idle, poor acceleration performance, increased fuel consumption and even an illuminated check engine light.

If any of these symptoms occur then it’s important to check your vehicle’s ignition coils immediately as they may need to be replaced or repaired.

2. Clogged Fuel Filter

Engine shaking when accelerating is a common issue that can be caused by many different factors. One of the most common causes is a clogged fuel filter, which blocks the flow of fuel to the engine.

A clogged fuel filter puts extra strain on your engine, making it hard for it to receive enough gasoline in order to properly function.

This can lead to an unstable idle, jerking during acceleration, and reduced performance overall.

It’s important for drivers to regularly check their vehicle’s fuel filter and replace it according to their car’s recommended maintenance schedule.

If you suspect that your vehicle has a clogged fuel filter, take it in for service as soon as possible so the problem can be diagnosed and fixed before more serious damage occurs.

3. Dirty Air Filter

Engine Shaking is a common car problem that can be caused by a dirty air filter.

The air filter cleans the air entering the engine and helps to increase fuel efficiency and performance.

If the air filter becomes clogged with dirt, debris, or other contaminants, it can cause an engine misfire which will result in shaking and poor acceleration.

When a vehicle’s air filter needs to be replaced, there are several signs that you should look out for. These include reduced power when accelerating, decreased fuel economy, black smoke from your exhaust pipe, and strange noises coming from under the hood of your car.

It is important to address these issues as soon as possible so you can prevent further damage to your engine.

Replacing a dirty air filter with a new one will ensure that your engine continues running smoothly, delivering optimum power output while protecting other sensitive components from damage due to unclean surfaces or particles entering the system. It’s important for drivers do regular checks on their filters themselves or take their vehicles into an au

4. Worn Out Engine Mounts

The Issue can be due to a number of factors, but one of the most common is worn out engine mounts. Engine mounts are components that keep the engine in place and dampen vibration to ensure the rest of the vehicle isn’t affected by it.

When these components start to wear down, they will cause more movement from the engine which will then cause vibrations that can be felt throughout the car and even create a shaking feeling when accelerating.

To determine if worn out engine mounts are causing your vehicle’s shaking, there are several signs you should look for.

These include louder than normal noises coming from underneath your hood, increased vibration in other parts of your car such as the steering column or dashboard, as well as a noticeable shifting or rocking motion when applying pressure on the accelerator pedal.

If you do notice any damage or looseness, it may be time for a replacement as failing engine mounts will only worsen over time and lead to further issues such as leaking fluid from hoses and even misfiring spark plugs.

Replacing them quickly is important in order to prevent potentially costly repairs down the line – so get those faulty mounts fixed before they become an even bigger problem!

5. Injector Issues

Driving a car with an engine that shakes when accelerating can be quite unnerving.

It could be due to an injector issue, which generally happens when the fuel injectors malfunction and don’t provide the right amount of fuel to the engine.

As a result, the engine will shake or vibrate at irregular intervals during acceleration.

In order to diagnose and repair this issue, it’s important to understand what causes injector problems in the first place.

Common causes include clogged or dirty fuel filter, faulty wiring harness or electrical connections, damaged or worn out parts like spark plugs and O-rings, as well as low levels of oil or coolant in the vehicle. In addition, some issues may stem from using poor quality fuel additives or incorrect octane rating for your car’s needs.

6. Clean The EGR Valve

Vehicle Engine shaking can be caused by several underlying issues, one of which is the EGR (Exhaust Gas Recirculation) valve.

The EGR valve helps reduce emissions from the engine by allowing some exhaust gases to recirculate back into the intake manifold for another round of combustion.

EGR valve works by redirecting exhaust gas back into the engine which helps reduce emissions and keeps your vehicle’s temperature regulated.

It’s important to check that the valve is working properly because if it isn’t, it can cause issues with how your engine runs and can even lead to potential damage.

If its not functioning properly, it can cause excessive vibration and shaking in the engine when accelerating or idling.

The good news is that cleaning the EGR valve only takes a few simple steps and doesn’t require any special tools or knowledge of mechanics.

You’ll need to remove the air filter housing in order to access the valve, then use compressed air or an appropriate solvent cleaner to remove any built-up dirt and debris from inside it.


If your engine is shaking when you accelerate, it’s time to take action. Don’t wait for the problem to worsen – the longer you put off a repair, the more costly and complicated it can become.

Invest in an inspection from a qualified mechanic as soon as possible to identify any underlying issues and determine what needs to be done to get your vehicle running smoothly again.

Whatever repairs are necessary, don’t forget that taking care of them promptly will save you money and inconvenience down the road (or highway).
