Absolutely. Worn-out o r dirty spark plugs result in poor combustion, leading to misfires and sputtering—especially during cold starts o r under load.

Signs of Faulty Spark Plugs:

Hard starts

Rough engine sound

Reduced fuel efficiency

Check engine light if installed aftermarket

Fixes:

Inspect and replace spark plugs every 10,000–15,000 km or sooner if using lower-quality fuel.

Check for correct plug gap and heat range suitable for Khyber.

Also inspect ignition wires and distributor cap for cracks o r wear.
