How can Karvaan owners identify early signs of spark plug problems before performance s?

Early warning signs like delayed starts, vibration, and poor pickup often go unnoticed. What simple checks can Karvaan drivers do themselves before visiting a workshop?

Look for these signs:

Vibrations at idle

Delayed o r rough engine start

Engine knocking o r jerking

Low pickup even with light load

Increased fuel usage

DIY checks:

Remove and inspect plug color black = carbon fouling

Check for cracks o r worn electrodes

Use a spark tester tool available online o r in auto shops
