What is the P0307 Code?
The P0307 code indicates a cylinder 7 misfire detected. This means that the engine control module (ECM) has identified that the engine is not firing properly in cylinder number 7.

- Fuel Injector Problems: A clogged or faulty fuel injector can prevent the proper amount of fuel from reaching 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 in the cylinder can also cause misfires.
- Faulty ECM: In rare cases, the engine control module itself may be faulty.
