...spark plug leads.? IN couple of thousand KM, the car is not getting smooth in road, and consume more fuel. If I add premium unleaded, it is better than the normal unleaded. But If I changed all spark plugs and leads at a time there is not any problem for 3000 to 4000 KM. I add fuel injection cleaner liquid in my petrol tank but it doesnot help.
