Hello All, my car runs smooth on LPG. But it's been a while since i drove my car on fuel . i have automatic LPG system which means the car starts on fuel. however, i'm noticing when i fully drive on fuel the acceleration is not getting the force like it used to and it is cluttering a bit. The moment i switch to LPG, it runs very smooth and picks up very well. before taking to garage, it would be great if i have some idea about the problem otherwise they will just rip me off. i assume it is some dirt. any suggestion would be appreciable. thanks
