Diagnosing bad spark plugs

Spark plugs get us going from a to b, but why are they sometimes missed?

It is advised that all spark plugs are checked at regular service intervals with visual inspections. These inspections can be the difference between a car coming in once a year or coming in once it’s stopped altogether.

If the spark plug fails, they should always be changed in pairs. Pairing spark plugs ensures they are working at their optimal performance with the same electrical resistance pulsing through.

Use this handy guide to identify the cause, effect, and approach needed to diagnose issues.
