    Default Vibration in XLI at slow speed

    When i converted XLI to CNG, its rpm dropped to around 700 and slight vibrating sound started coming from dash board. Vibration disappeared immediately when speed is increased.
    However after 1-2 months, now when ever i press accelerator , at 1200 rpm dash board vibrates and persists at same rpm. Its a new XLI and sound is irritating when driving at slow speed. I have checked with Toyota motors but still problem is there, any solution...

    u sure its not the cassetes or coins in the dash making the sound. actually the dash is also low quality. i witnessed untidy gaps in vents etc in brand new cars.
    Life is short and very unpredictable just like a Quarter mile .....

    I think fuel quality would also have a little to do with this. My XLi used to sometimes shut down during idle since there was all this kachra in the fuel (it's very common in ISB to get scammed in fuel)
    Yours is CNG, so i don't know, that may not be the problem with your car...

    CNG k saath waisay yeh hota hai...


    I think tuning karwani parey gi but i'm not a CNG expert...

    i am sure there r no coins etc which are producing sound. I have carried out tuning as well,,but no improvement. I'll try to change cng gas supply pressure/flow, may be it helps......
    What is your petrol consumption in local area? Mine have been doing 7 km /ltr when it was new, that was too low in my opinion
    Can you recommend some good tyres? I am using the originals and the car always skids if i apply hard brakes above 70.....

    have your engine mounts inspected, as well as your clutch/pressure plate/bearing.

    DUDE IF YOUR CAR VIBRATES ON PETROL AND NOT ON CNG THEN I CAN'T GIVE ANY SOLUTION BUT IF YOUR CAR VIBRATES ON CNG AND NOT ON PETROL THEN THE PROBLEM LIES WITHIN THE CNG INSTALLATION AND SETTINGS

    HAVE IT CHECKED BY A PROPER CNG CENTRE

    As posted above, i havent checked engine mounting and clutch plate...
    Problem is with CNG only, not with petrol

    If i increase the speed by screw at CNG kit, vibration disappers above 1200 rpm, but 1200 rpm idle speed is not recommended, it should be lower

    CNG kit is not computerized, it has manual adjustments

    Who is the expert CNG mechanic in Lahore,,,or in multan (i often visit multan)?
