Yes, the symptoms youre hearing are accurate. Pakistani Alsvin owners frequently report:

Engine misfiring

Rough idling

Delayed acceleration o r throttle response

Reduced fuel economy

Engine warning light check engine lamp

These symptoms typically begin appearing around 15,000–20,000 km much earlier than expected, especially in urban traffic o r when using lower-grade fuel.
