Hi there,Usually f the light is flashing it indicates a misfire on one of the cylinders. This will cause a reduction in power of 25%. The light staying on will provide you with a code to tell you which cylinder is the problem. In most cases the issue can be or will be on e of the ignition coils. Sometimes with the engine running if you spray a little water on the coils you can see it arcing. This would be the cause of the problem. You can also pull the coils and inspect the rubber boots where they go to the spark plugs. If there is oil on them it can cause the issue or you might see a burn mark. Replace said coil and it should solve the problem.What happens next:Just Answer will now charge you for the full amount of your question.My goal is to provide you with 5-star service.
