What is the solution for fault code P0302?

[VanElijah]

Fault code P0302 indicates a misfire in the second cylinder of the engine. In this case, it is necessary to inspect the intake, exhaust, ignition, and fuel injection systems. After identifying the faulty component, replace the damaged part to resolve the issue. Engine misfire refers to a situation where one or more cylinders are not functioning properly, leading to reduced engine smoothness and decreased power output. Most engine misfires are caused by damaged ignition coils or spark plugs. The ignition system of a car engine mainly consists of spark plugs and ignition coils. Spark plugs are wear-and-tear components that require regular replacement. If spark plugs are used for an extended period, the electrode gap may widen, and carbon deposits may accumulate on the electrodes, which can affect the spark plug's ignition performance.
