What Causes Misfire in Cylinder 2 of the New Fit?

[SanMatthew]

Possible causes include carbon buildup in the engine, weak spark plug ignition energy, or a depleted battery. Carbon buildup in the engine: If accompanied by slight shaking at idle, cleaning the throttle body and fuel injectors should resolve the issue. Weak spark plug ignition energy: Failure to replace spark plugs after their maintenance interval can lead to severely reduced ignition energy, resulting in misfires. Insufficient low fuel pressure: Inadequate pressure in the low-pressure fuel system directly causes the engine to misfire during secondary ignition. Specifically check the fuel pressure regulator, fuel pump, fuel filter, and internal fuel lines. Depleted battery: This can be resolved by jump-starting the vehicle using another car or battery.
