Engine Light Blinking and Car Shaking: Causes and Solutions
1. Engine Misfire
A misfire occurs when one or more cylinders in the engine fail to fire properly. This can cause the engine to shake and the check engine light to blink. Misfires can be caused by a variety of factors, including:
- Faulty spark plugs
- Worn ignition coils
- Leaking fuel injectors
- Clogged air filter
2. Fuel injector issues
Fuel injectors are responsible for delivering fuel to the engine’s cylinders. If a fuel injector becomes clogged or damaged, it can cause the engine to run lean or rich, which can lead to shaking and a blinking check engine light.
3. Faulty oxygen sensor
The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gases. If the oxygen sensor fails, the engine may run rich or lean, which can cause shaking and a blinking check engine light.
4. Faulty mass airflow sensor
The mass airflow sensor measures the amount of air flowing into the engine. If the mass airflow sensor fails, the engine may run rich or lean, which can cause shaking and a blinking check engine light.
5. Vacuum leak
A vacuum leak can cause the engine to run lean, which can lead to shaking and a blinking check engine light. Vacuum leaks can be caused by a variety of factors, including:
- Loose or damaged hoses
- Cracked or broken intake manifold
- Faulty PCV valve
6. Electrical problems
Electrical problems, such as a loose battery terminal or a faulty alternator, can also cause the engine to shake and the check engine light to blink.
What to do if your engine light is blinking and your car is shaking
If your engine light is blinking and your car is shaking, it is important to have the problem diagnosed and repaired as soon as possible. Driving with a blinking check engine light can damage your engine and lead to more expensive repairs.
Here are some things you can do if your engine light is blinking and your car is shaking:
- Pull over to a safe location and turn off the engine.
- Check the engine oil level and coolant level.
- Inspect the spark plugs and ignition coils.
- Listen for any unusual noises coming from the engine.
- Call a tow truck or have the car towed to a mechanic.
It is important to note that these are just some of the possible causes of a blinking check engine light and car shaking. The specific cause of the problem will vary depending on the make and model of your car.
