problem is electrical as its on both petrol and gas and on low revs when there is heavy compition for current in all items and i doubt that not all four cylinders are firing, and once again as problem is on cng aswell anything related to injectors is also ruled out, check your spark plugs one might be short or anything can go wrong with it, do check spark plugs cables and distributor. i would suggest you see an electrician, any indication on cluster there??
