    Default Urgently Need HELP Toyota Vitz Petrol Problem for few minutes after starting

    Hey guys, I have toyota vitz model 1999 1000cc.
    It on CNG and i do drive on petrol sometimes and you must know that these cars always starts on petrol and than convert to CNG automatically after sometime, so it was going ok since last 2 months, in last 2 months I've experienced strange problem i.e. whenever i start my car it gives strange sound like it was going to off automatically and when i try to give manual race it doesn't pick it and vibrates and gives a sound like it was going to shutt down and sometimes it does shutt down when i try to give race to give the engine the power to get smooth. It only happens a few minutes and afterwords it runs smoothly.
    I've get it checked by mechanic and he said its fuel filter needs to be replaced and i got it replaced but still the problem was there, than again i get to the mechanic and he said i need to change the fuel motor as it gets weak and than i replaced the fuel motor but still the problem is there.
    Can anyone please help me out???
    This only happens on petrol and for very few minutes after i start the car and very rarely happens while driving.
    It nevers happens on CNG.
    Please guys help me out or tell me about a mechanic who can fix it well.
    You can also contact me on my number 0321-4055485
    please i need sincere advice
    Thanks in advance
