Reasons for Misfire in Cylinder 1 of the Mazda 3 Axela

[Nancy]

The reason for misfire in cylinder 1 of the Mazda 3 Axela is a clogged fuel injector. Poor spark plug contact: If ignition fails momentarily, a cylinder misfire will occur. Excessive self-induced voltage in the fuel injector: This can cause sticking in the next working cycle. Poor heat dissipation in the transistor: Inadequate heat dissipation of the transistor inside the ECU leads to non-operation of the ignition coil. Insufficient cylinder pressure results in ignition failure. Check the circuit: Inspect for aged wiring with exposed or leaking insulation. After confirmation, rewire and repair. Replace spark plugs: If internal components of the ignition coil or spark plugs are damaged, replace them after confirmation. For loose connectors, manually reinforce all contact points.
