Mechanics sometimes trace spark plug issues back to weak ignition coils o r loose wiring. Have Karvaan owners found such related faults in their vans?

Yes. A weak ignition coil o r loose plug wire causes:

Low spark energy, leading to incomplete combustion

Excess fuel buildup, fouling the spark plugs

Backfiring o r knocking

Some Karvaan owners discovered coil failure after multiple plug changes. So, always check the coil and wiring if spark plug wear is too frequent.
