- OBD-II Code: Part of the vehicle's diagnostic system.
- Impact: Can lead to reduced engine performance and increased emissions.
Common Causes of P0302
Understanding the potential causes of the P0302 code can help you diagnose the issue more effectively. Here are some common reasons for a misfire in cylinder 2:

- Ignition Coil Issues: A malfunctioning ignition coil can lead to weak or no spark in the cylinder.
- Fuel Injector Problems: A clogged or faulty fuel injector may not deliver the proper amount of fuel to the cylinder.
- Vacuum Leaks: Leaks in the intake manifold or vacuum hoses can disrupt the air-fuel mixture.
- Engine Mechanical Issues: Problems such as low compression or valve issues can also cause misfires.
