Jeep Check Engine Light Flashing and Car Shaking
What it Means
If your Jeep’s check engine light is flashing and the car is shaking, it means that there is a serious problem with the engine. The most likely cause is a misfire, which occurs when one or more of the engine’s cylinders is not firing properly. This can cause the engine to run rough and lose power, and it can also lead to other problems, such as engine damage.
Causes
There are a number of things that can cause a misfire, including:
- Faulty spark plugs or wires
- Bad ignition coil
- Vacuum leak
- Fuel injector problems
- Compression problems
Symptoms
In addition to the check engine light flashing and the car shaking, other symptoms of a misfire can include:
- Rough idle
- Loss of power
- Hesitation or stumbling during acceleration
- Poor fuel economy
- Backfiring
Diagnosis
To diagnose a misfire, a mechanic will typically use a scan tool to read the engine’s computer for trouble codes. The trouble codes can help to identify the specific cause of the misfire.
Repair
The repair for a misfire will depend on the underlying cause. In some cases, a simple repair, such as replacing the spark plugs or wires, may be all that is needed. In other cases, a more complex repair, such as replacing the ignition coil or fuel injector, may be necessary.
Prevention
There are a few things you can do to help prevent misfires, including:
- Regularly maintain your Jeep according to the manufacturer’s recommended maintenance schedule.
- Use high-quality spark plugs and wires.
- Avoid driving in dusty or dirty conditions.
- If you notice any symptoms of a misfire, have it diagnosed and repaired as soon as possible.
Conclusion
If your Jeep’s check engine light is flashing and the car is shaking, it is important to have it diagnosed and repaired as soon as possible. Misfires can cause serious engine damage, so it is important to address the problem as soon as possible.
