In both cases, you should pay attention to the cause and get it repaired as soon as possible. There are many types of concerns that a car owner experiences with the vehicle in a lifetime and check engine light blinking and car shaking is one of them.
Today, we will understand what this flashing and shaking could possibly mean and what your options are. Let’s head to the concern-
Check Engine Light Blinking And Car Shaking: Understanding The Process!
Different sensors and actuators in your car work to detect any malfunctioning and register this information with your car’s computer system. In the case of a shaking car, the check engine light appears on your dashboard.
When this Check Engine Light blinks continuously instead of appearing steadily, it represents a more serious issue rather than one that can be avoided. Hence, taking the car to a professional is always a wise move. However, you should always have clarity about the causes that make an issue happen to your car.
The Possible Reasons Behind A Shaking Car
The primary culprit that makes your check engine light blinking and car shaking is a malfunctioning cylinder. Every cylinder in your engine is supposed to play its part or fire to pass the mixture of fuel and air in the system. When the cylinder does not work as expected or it does not pass the fuel and air every time the crankshaft turns, it misfires. As a result, the engine runs rough and it makes the overall car shaking.

Now, why the cylinder does not play its part can be because of several reasons. The first reason can be the worn spark plugs. In most cases, these plugs work well for up to 100,000 miles and if you do not replace them timely, they are likely to create an issue with the cylinder’s functioning.
The second reason can be the out of order coils. Coils are responsible to produce the spark that the cylinder needs to fire whenever the crankshaft happens. Thus, you can have the coil checked too by a repairer and go with the replacement if it is needed.
Some More Reasons!
The third reason on car shakes when driving and check engine light is on can be a faulty intake manifold gasket. These gaskets work as a seal and when the seal loses its ability, it makes the engine to overheat. Other than an overheating engine, if you can smell the coolant leak, it is a symptom that there is something wrong with the gasket.
A broken engine mount also serves as a reason that is enough to produce vibration while you drive. The mount keeps the engine attached with the frame of the car. And when the mount wears off, you experience a shaking car.
All these can be reasons why your cylinder does not fire when it should. This issue needs to be tackled right away as driving the car with the problem still damages the components further. As a result, it charges you more dollars, and that is not what anyone wants.
What Are Your Options On Any Of These Issues?
The first and recommended option for car shaking and engine light on is to take the car to a local dealership or the repair center where a particular brand of cars are repaired. As the people working here are professionals and they have the knowledge about a particular brand, it comes as an advantage.
The second option is about taking your car to an independent car repair center. Usually, repairers working at these centers work all the vehicles regardless of the brands. Plus they charge you less than local dealerships. Read more about maintaining your car well here Maintenance Tips.
As the third option, you can go for DIY if you have sound knowledge about reading the code form using the OBD-II scanner and perform the repair accordingly. There are many websites out there selling the scanners and these are usually cheap devices. Nonetheless, an inexperienced car owner should not opt for the DIY option. It can do more damage to your car.
Now you know that faulty spark plugs, worn out coils or a leaking gasket can be the reason for check engine light blinking and car shaking. Observe the dashboard lights regularly and note which symbol is showing up in which color.
When you see any of the symbols in white, blue, and green lights, there is nothing to be worried about. However, yellow and red lights recommend taking your car for a checkup. Here, the self-diagnostic system can be a great help but if you do not possess enough knowledge, we recommend you to visit car care professional.
