Car Shaking and Check Engine Light on After Oil Change: Troubleshooting Tips & Solutions

After an oil change, if your car is shaking and the check engine light is on, it may indicate an unresolved issue with the vehicle. This occurrence could be caused by a variety of factors, including a loose or damaged component or a problem with the engine’s sensors.

It is crucial to address the problem quickly, as ignoring the issue could lead to further damage and costly repairs.

Why Would a Check Engine Light Come on After an Oil Change?

Car shaking and check engine light can be triggered after an oil change due to various reasons like loose parts, dirty fuel injectors, or engine misfires. It is crucial to identify and address these causes promptly to prevent further damage to your car.

Car shaking and the appearance of a check engine light after an oil change can be a cause for concern. It is important to understand the underlying issues that may lead to such symptoms in order to accurately diagnose and resolve the problem.

In this section, we will discuss the common causes of car shaking and check engine light, explore their relationship, and provide diagnostic steps to identify the root causes.

Common Causes Of Car Shaking And Check Engine Light:

• Faulty spark plugs: Damaged or worn-out spark plugs can cause uneven engine combustion, resulting in car shaking and triggering the check engine light.
• Ignition system issues: Problems with the ignition coil, ignition wires, or distributor can lead to engine misfires, leading to car shaking and the illumination of the check engine light.
• Fuel system problems: A clogged fuel filter, malfunctioning fuel injectors, or a defective fuel pump can disrupt the fuel supply, impacting engine performance and resulting in shaking and the activation of the check engine light.
• Vacuum leak: An intake manifold or vacuum hose leak can introduce excessive air into the engine, disrupting the air-fuel mixture and leading to rough idling, shaking, and the check engine light turning on.
• Engine misfire: A misfiring engine, caused by issues such as a faulty fuel injector or ignition system, can create an imbalance and cause the car to shake while triggering the check engine light.

How Car Shaking Relates To The Check Engine Light?

Car shaking and the illumination of the check engine light often go hand in hand. The shaking indicates an issue with the engine’s performance, while the check engine light serves as an indicator that the onboard diagnostic system has detected a fault.

The check engine light can provide valuable information through diagnostic trouble codes (DTCs), aiding in the identification of the underlying issue causing the car to shake.

Diagnostic Steps To Identify The Underlying Issues:

• Retrieve diagnostic trouble codes: Use an onboard diagnostic scanning tool to read the DTCs stored in the vehicle’s computer system. These codes can provide valuable insights into the specific issue triggering the check engine light.
• Inspect spark plugs and ignition system: Check the condition of the spark plugs and inspect the ignition system components for any signs of damage or wear. Replace any faulty parts as necessary.
• Check the fuel system: Test the fuel pressure to ensure it is within the manufacturer’s specifications. Additionally, inspect the fuel injectors, fuel filter, and fuel pump for any potential problems.
• Examine the vacuum system: Inspect the intake manifold and vacuum hoses for any signs of leaks or damage. Repair or replace any faulty components.
• Perform a comprehensive engine inspection: If the above steps do not uncover the issue, it may be necessary to conduct further diagnostic tests, such as checking the engine’s compression and conducting a thorough inspection of the engine components.

By understanding the common causes of car shaking and check engine light, as well as following the diagnostic steps outlined above, you can effectively identify and resolve the underlying issues. Addressing these problems in a timely manner will not only eliminate the shaking and turn off the check engine light but also ensure the optimal functioning and performance of your vehicle.

Troubleshooting Tips For Car Shaking And Check Engine Light

Experiencing car shaking and a check engine light after an oil change? Read on for troubleshooting tips to identify and resolve these issues.

Checking For Loose Or Damaged Components:

• Check the battery terminals to ensure they are securely connected. Loose or corroded terminals can cause electrical issues and trigger the check engine light.
• Inspect the spark plug wires for any signs of damage or wear. Faulty wires can lead to misfires and shaking of the car.
• Examine the vacuum hoses for cracks or leaks. Leaking hoses can disrupt the airflow and result in engine shaking.
• Check the ignition coil for any visible damage. A faulty ignition coil can cause engine misfires and shaking.

Testing And Replacing Ignition System Components:

• Test the ignition coils to determine if they are functioning properly. Faulty ignition coils can cause engine misfires, leading to car shaking and the check engine light coming on.
• Check the spark plugs for signs of wear or damage. Worn-out spark plugs can result in engine misfires and shaking.
• Replace the ignition control module if necessary. A faulty module can cause irregular sparks and engine misfires.

Inspecting And Cleaning Fuel System Components:

• Inspect the fuel filter for any clogs or blockages. A clogged fuel filter can disrupt fuel flow and cause engine misfires.
• Check the fuel injectors for any signs of dirt or debris. Dirty injectors can lead to poor fuel atomization, resulting in engine misfires and shaking.
• Clean the throttle body to remove any carbon buildup. A dirty throttle body can affect air intake and cause engine shaking.
• Inspect the fuel pump for proper functioning. A faulty fuel pump can result in insufficient fuel delivery and engine misfires.

Evaluating The Condition Of The Engine Mounts:

• Inspect the engine mounts for any signs of damage or wear. Broken or worn-out mounts can cause excessive engine movement, leading to car shaking.
• Check the transmission mounts as well, as they can also contribute to car shaking if damaged.
• Ensure that the engine mounts are properly aligned and tightened. Improper alignment can lead to excessive vibration and shaking of the engine.

Remember, if you are not comfortable troubleshooting these issues yourself, it’s always best to consult with a professional mechanic. They have the expertise and resources to accurately diagnose and fix the problem, ensuring the smooth operation of your vehicle.
