Car Bucking Check Engine Light: Causes and Solutions
If your car is bucking and the check engine light is on, it means that there is a problem with your vehicle’s engine. There are several potential causes of this problem, and it is important to have it diagnosed and repaired as soon as possible.
One of the most common causes of car bucking and check engine light is a problem with the spark plugs or ignition coils. The spark plugs are responsible for igniting the fuel in the engine, and if they are not working properly, the engine will not be able to run smoothly. The ignition coils are responsible for providing the spark plugs with the electricity they need to function, so if the ignition coils are not working properly, the spark plugs will not be able to ignite the fuel.
Another common cause of car bucking and check engine light is a problem with the fuel system. The fuel system is responsible for delivering fuel to the engine, and if there is a problem with the fuel system, the engine will not be able to get the fuel it needs to run properly. The fuel system can be clogged, dirty, or leaking, which can all lead to problems with the engine.
Other potential causes of car bucking and check engine light include:
- Vacuum leak
- Exhaust leak
- Clogged catalytic converter
- Faulty oxygen sensor
- Bad throttle position sensor
