    for CNG the timing is advanced controlled by ADVANCER if it is not installed then it is manually done by the 'Ustaad' so you hear knock when on petrol and ride is uneven.

    if advancer is there check for malfunction, also for the vibration check the engine & transmission mountings.

    Check air filter assembly for blockage,some times cng technicians block the air intake to adjust idle speed on cng.Remove blockage if any,and get cng flow adjusted without blocking air intake.
    Never loose hope in life,every step gives u something.

    do get your fuel pump and injectors checked, make sure you drive around 5-6 km's a day / week to keep the fuel rolling through

    new city is famous for malfunctioning of fuel gauge if put CNG in it.
    Failing to prepare is preparing to fail.

    City AT on CNG will have this issue. It requires proper CNG settings. Avoid CNG on AT if possible.
