Some users report misfires, rough idling, and weak acceleration due to faulty plugs. Is this an issue of poor-quality spark plugs o r unsuitable fuel conditions in Pakistan?

Many MG HS drivers report misfires, rough idling, and weak acceleration. The reasons are twofold:

Pakistan’s low-quality petrol with impurities damages plugs faster.

The HS’s turbo engine requires high-performance plugs, which wear out quickly if the fuel is not clean.
