My suggestion to u is not to switch off and on a/c so frequently.
Cultus is very delicate and may cause damage of your dynmo cutout or some generator alternator issue during load shifts
When u will get time, get it scanning report via Efi ecu scanner. It will give u true picture of your car.
Anyways minor jerking is no issue but ideally there should be no jerks.
Also get it tuning after oil change which should include following jobs:
Cleaning of Spark plugs,plug wires and coils
Removal of oil from cng cylinder
Draining of oil from cng kit
Setting and tuning of car on both Petrol and cng
Insha Allah jerks will go
