Can a failing ignition coil lead to irregular engine firing and sputtering in Changan Kalam models used across Pakistan?

Some workshops replace ignition coils frequently. Is the ignition system under-designed for local load conditions?

✅ Yes — ignition coil failure is another key cause.

Signs:

Engine shaking o r shuddering

Check engine light

Backfiring o r hesitation

Pakistani roads with high temperatures and bumpy terrain can shorten coil lifespan.

🛠️ Mechanic advice: Replace all coils together if one fails, especially after 40,000–50,000 km.
