- 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, leading to misfires.
- Engine Mechanical Issues: Problems such as low compression or valve issues can also cause misfires.
