- Loose or disconnected spark plug wires: Make sure that the spark plug wires are properly connected to the spark plugs and that they are not loose.
- Incorrect spark plug gap: The spark plug gap is the distance between the center electrode and the ground electrode of the spark plug. If the gap is too wide, the spark will be weak and the engine will misfire. If the gap is too narrow, the spark will be too strong and could damage the engine.
- Worn-out spark plugs: Spark plugs can wear out over time, which can cause the engine to sputter. If the spark plugs are old, it is a good idea to replace them.
- Faulty ignition coil: The ignition coil is responsible for delivering electrical current to the spark plugs. If the ignition coil is faulty, it can cause the engine to sputter.
If you are unable to find and fix the source of the sputter, it is recommended to take your vehicle to a qualified mechanic for further diagnosis and repair.
