    its common. with CNG in Vitz. altho i dont have cng in mine so people having it would guide you better what can be done to rectify this issue as its a safety hazard.
    Get over the fact that Xli lacks power windows, Its an Xli because it lacks thoose features or else it would be a Gli or an Altis if had all the goodies.

    its not the fault of Vitz...car has nothing to do with it! who said you to install CNG...issue is one of the side effect of that CNG installation.
    if you want to be safe.drive it on Petrol.everything will be saved.life of the engine will enhance and many more

    @all^ understand the iuse first before giving any suggestions. The poster is facing the issue on CNG only. The system is okay. Bleeding it wont help. Its some electrical issue in CNG Vitzes
    Get over the fact that Xli lacks power windows, Its an Xli because it lacks thoose features or else it would be a Gli or an Altis if had all the goodies.

    @op. its a problem with low idle and low vacuum. on cng...the engine is not able to make enough vacuum.
    so there is very less vacuum going to the break booster. it feels as if you are pressing the breaks when the car is not started.
    what you need to do is get a vacuum pump installed in the vacuum like to the break booster.. and that will solve your problem instantly

    You just need to perfectly tune your car on CNG (if you have it in your car). Never reduce the amount of gas flow on idle to the point where your car struggles to breath.

    Get your idle speed checked on CNG.
