Our team of ASE-certified technicians, with their expertise and dedication, are here to assist you with all of your Mercedes repair needs.

Common Causes of Misfires

You may be wondering what causes your automobile's engine to misfire. In basic terms, the underlying issue will interfere with combustion. For instance, aging/worn spark plugs may fail to produce the spark necessary for igniting fuel in the cylinder. Likewise, clogged or failing fuel injectors can cause misfires because the fuel supply entering the cylinders is insufficient to facilitate combustion. Another potential cause is a poorly working ignition coil. This component is responsible for converting the low-voltage electrical power coming from the battery into the higher voltage needed to create the spark in the plugs. The mass airflow sensor measures the amount of air entering. This is important for achieving the optimal air-to-fuel mix. If this part goes terribly, it can lead to misfiring. Yet another is a vacuum leak that allows too much air to enter as compared to the amount of fuel. Regardless of whether one of these creates the engine misfiring condition or it's caused by something else, your car's check engine light is likely to illuminate.
