Check Engine Light Car Sputtering
If your car is sputtering and the check engine light is on, it’s important to take it to a mechanic as soon as possible. This could be a sign of a serious problem, such as an engine misfire, a fuel injector problem, or a problem with the ignition system.
Engine Misfire
An engine misfire occurs when one or more of the cylinders in your engine is not firing properly. This can cause the engine to run rough, sputter, and lose power. If you’re experiencing an engine misfire, you may also notice a decrease in fuel efficiency and an increase in emissions.
Fuel Injector Problem
Fuel injectors are responsible for delivering fuel to the engine’s cylinders. If a fuel injector is clogged or damaged, it can prevent the engine from getting the fuel it needs to run properly. This can cause the engine to sputter, hesitate, and lose power.
Ignition System Problem
The ignition system is responsible for providing the spark that ignites the fuel in the engine’s cylinders. If there is a problem with the ignition system, it can prevent the engine from starting or running properly. This can cause the engine to sputter, backfire, and lose power.
Other Possible Causes
In addition to the above, there are a number of other possible causes of a check engine light and car sputtering, including:
- Vacuum leak
- Exhaust leak
- Catalytic converter problem
- Oxygen sensor problem
- Mass airflow sensor problem
- Throttle position sensor problem
What to Do
If your car is sputtering and the check engine light is on, it’s important to take it to a mechanic as soon as possible. The mechanic will be able to diagnose the problem and recommend the best course of action.
