i have got 2000 Model Baleno. there is some problem which i could figure out. Jerks and missing are the major problem and the car standing automatically accelerates and de-accelerate. Checked its injectors, there was rust gathered in them. Cleaned the injectors and then replaced the fuel tank because the old tank was itself rusty. After this car ran smoothly for few KMs. But again, starts jerking and switches off while running. after 2-3 sulfs, it starts again and then jerks etc. since after cleaning the injectors, the car ran few KMs on old fuel and fuel tank, I have asked the mechanic to re-clean the injectors.
if some one could understand this problem, please advice me.
