Its one of the maindrawback of using CNG kit.Though it can not be solved completely, can be minimised by regular servicing of conversion kit.

U can try resetting the car ECM.Driving in CNG mode effect the ECM. memory. This can be done by disconnectn the negative wire of the battery and pressing the brake pedal for 2-3 mins to completely drain out current from ECM.Then reconnect the battery and start the car.Now drive the car for at least 15 mins for the ECM to take ur driving style.I think this dhould solve ur problem.
