Faulty ignition components are a common cause of starting difficulties o r engine misfires in the JAC T6:

Worn o r dirty spark plugs: Can fail to produce a strong enough spark, causing misfires o r hesitation during acceleration.

Faulty ignition coils: Weak o r failing coils may produce inconsistent sparks, leading to stalling, rough running, o r hard starts.

Damaged ignition wiring o r connectors: Loose, corroded, o r damaged wiring can interrupt the ignition signal, resulting in intermittent misfires.

Sensor issues: Malfunctioning crankshaft o r camshaft position sensors can affect spark timing, reducing combustion efficiency.

Solutions / preventive measures:

Inspect and replace spark plugs at recommended intervals.

Check ignition coils and wiring for damage o r corrosion.

Scan the ECU for ignition-related fault codes to identify failing components early.
