Car Sputtering Check Engine Light on

Last Updated on June 20, 2023 by Ryan

If the check engine light on your car is illuminated and it is sputtering, there are a few steps you should take. Firstly, ensure that the fuel tank has sufficient gasoline in it as running out of gas can cause this issue. Secondly, inspect all spark plug wires for any damage or corrosion which could inhibit its performance.

Thirdly, check the air filter to make sure that it’s not clogged up with dirt and debris which would also impede performance. Lastly, have an auto mechanic inspect the vehicle for any other underlying issues such as a bad oxygen sensor or catalytic converter malfunctioning. Once these steps have been completed then you should be able to identify why your car is sputtering and get it fixed accordingly by a certified technician.

If your car’s Check Engine light is on, and it’s sputtering or running rough, then you should take it to a mechanic right away. Your car could be showing signs of a more serious issue that needs to be addressed before it leads to costly and irreparable damage. A qualified mechanic can quickly diagnose the problem and get your car back in top condition.

How To Tell If Your Engine Is Sputtering-Engine Problems

How Much Does It Cost to Fix an Engine Sputter?

The cost of fixing an engine sputter will vary depending on the severity of the problem and what type of repairs need to be made. If it is just a minor issue, such as a faulty spark plug or air filter, then the repair costs could be relatively low – up to $100 for parts and labor. However, if more extensive repairs are required, such as replacing fuel injectors or cleaning out carbon deposits from your cylinders, then you may end up paying several hundred dollars in repairs and labor.

In some cases, especially with older vehicles that have been neglected over time, you may even find yourself needing to replace the entire engine which can reach into the thousands of dollars range.

Why is My Car Sputtering And Shaking?

Your car is sputtering and shaking because it could be experiencing a number of different issues. The most common cause is an issue with the fuel system such as a clogged fuel filter, faulty spark plugs or wires, dirty injectors, worn-out distributor cap and rotor, or a bad oxygen sensor. Other potential causes include misfiring cylinders due to low compression in the engine caused by worn piston rings or valves, vacuum leaks in the intake manifold or air ducts, leaking head gasket seals causing coolant to enter the cylinders and disrupt combustion processes.

Lastly, it could also be related to low transmission fluid levels that can affect power delivery from your engine. To identify which of these potential problems is causing your car’s sputtering and shaking symptoms you should take it into a qualified mechanic for diagnosis and repair.

Why Does My Car Engine Sputter When I Accelerate?

Your car engine may be sputtering when you accelerate due to a number of causes. It could be something as simple as using the wrong grade of fuel, or an issue with your air filter being clogged and not allowing enough air into the engine. Other potential causes include faulty spark plugs, a bad mass airflow sensor, low oil levels, or even contaminated gasoline.

To properly diagnose why your car is sputtering when accelerating, it’s best to take it to a professional mechanic who can pinpoint exactly what’s causing the problem and get it fixed quickly and safely.

Car Sputters When Starting Then Runs Fine

Starting a car and hearing it sputter can be quite alarming. This could indicate an issue with the fuel system, ignition system, or air intake. If your car is sputtering when you start it but runs fine afterwards, then this could mean that there is an issue with the engine’s idle speed setting or that there is not enough fuel being injected into the cylinders of your engine.

It’s best to take your vehicle to a certified mechanic who can diagnose and repair any issues related to why your car is sputtering when starting up.

Car Sputtering No Check Engine Light

If your car is sputtering but there is no Check Engine Light illuminated, it could be caused by a number of things. Possible causes include blocked fuel injectors, clogged air filters, worn spark plugs or wires, bad oxygen sensors or a faulty catalytic converter. It’s important to have the vehicle checked out by a professional mechanic to determine the exact cause and make any necessary repairs.

Car Sputters When Accelerating at Low Rpm

If your car is sputtering when accelerating at low RPMs, it could be a sign of an issue with your fuel system. The most common cause of this type of problem is a clogged or dirty fuel filter that’s preventing the engine from receiving enough fuel. Another potential issue could be a bad spark plug, faulty air intake hose, carburetor adjustment problems or even an ignition timing-related issue.

To diagnose and fix the underlying cause of your car sputtering at low RPMs, you’ll likely need to have it looked at by a professional mechanic.


In conclusion, it is important to take the necessary steps when experiencing car sputtering and a check engine light. Diagnosing the issue and finding the source of the problem can help prevent further damage down the road. Additionally, regular maintenance will keep your vehicle running properly for years to come.

If you are unsure of how to address either of these issues, it is always best to consult with an auto professional who can provide insight into what needs to be done.
