A Genuinely Important Reason Not to Delay: Catalytic Converter Damage — Nissan Note Spark Plugs
This is genuinely worth acting on promptly: driving with worn spark plugs or failing ignition coils doesn't just cause a rough-running engine — unburnt fuel from a genuine misfire can pass through into the catalytic converter and damage it, turning a relatively inexpensive plug or coil fault into a considerably more expensive catalytic converter replacement if left unaddressed.
It's also worth knowing that the specific cylinder number reported in a misfire fault code isn't always fully reliable — the ECU can sometimes attribute a misfire to an adjacent cylinder rather than the one genuinely at fault.
Nissan Note Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
A worn set of spark plugs in the Nissan Note doesn't make itself obvious: idle roughens slightly, acceleration loses a bit of urgency, and both symptoms are easy to blame on something else entirely. Given how inexpensive the part is, it often gets neglected for far longer than it should.

Nissan Note Spark Plugs: What They Do
Every combustion cycle in the Nissan Note's petrol engine starts with a spark plug igniting the compressed fuel-air mixture, and their condition shapes efficiency, economy and smoothness directly. Diesel versions don't need them at all, relying purely on compression to ignite fuel.
