A Genuinely Important Reason Not to Delay: Catalytic Converter Damage — Nissan Pulsar 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 Pulsar Spark Plugs: A Cheap Part That Causes Expensive-Feeling Problems
On the Nissan Pulsar, there's rarely a clear signal when spark plugs wear out — just a rougher idle, marginally less pep off the line — vague enough to get pinned on other engine issues. Since the part costs so little, it's also one of the easiest things to keep putting off.

Nissan Pulsar Spark Plugs: What They Do
On the Nissan Pulsar, combustion efficiency, fuel economy and smooth running all trace back to spark plug condition, since these are what ignite the compressed fuel-air mixture in each cylinder. Petrol engines depend on them entirely — diesels skip spark plugs altogether, igniting fuel through compression instead.
