Go to enercon in melody or in G-10 near mari gas.He probably has opened too much gas,try reducing it.start the car when the RPM meter hits 3k (if it doesn't have one then just rev the car abit).start reducing the gas by tightening the screw between ur car's carburator and cng kit.there will be a point when RPM will go up,and u'll feel that car has become responsive,continue to tighten until the rpm starts to drop or car start making jerk like engine is struggling to run.Now loosen up the gas inlet screw until the car becomes light and responsive again.And that's about it.Give her a run and if u feel pick is less then loosen up the gas inlet screw by half cycle.Hopefully this will resolve ur issue.
