Sudden in Fuel Efficiency After Switching Between CNG and Petrol

Some drivers notice that after frequently switching between CNG and petrol, the car’s fuel average on both fuels becomes noticeably worse. The car may feel sluggish, idle roughly, o r produce a smell of unburnt fuel. This issue is more common in older Santro models with aftermarket CNG kits. What factors lead to this sudden decline in fuel efficiency, and what steps can be taken to resolve it?
