Why is Mazda 323f engine running rough?

A Mazda 323f engine may run rough due to several potential issues, such as a dirty or clogged fuel filter, faulty spark plugs, or ignition system problems. Additionally, issues with the air intake, such as a dirty mass air flow sensor or vacuum leaks, can disrupt the air-fuel mixture. Engine timing problems or a failing fuel pump can also contribute to rough running. Regular maintenance and diagnostics are essential to identify and resolve these issues effectively.
