Do drivers in Pakistan face sputtering issues in Changan Kalam after cold starts, especially during winter in northern regions?

Complaints of unstable idle and engine stalling are common. Is the choke o r fuel system not well-tuned for cold weather?

✅ Yes — especially in colder regions like Abbottabad, Murree, Swat, etc.

Complaints include:

Rough idle for first few minutes

Poor fuel combustion in cold engines

Reason: Weak ECU cold-start programming and no advanced choke control.

Fuel injection is not optimized for below-10°C starts.

🧊 Tip: Let the car idle 1–2 minutes after starting in winter to stabilize RPM.
