    Default Mehran suffers jerks above 100km/h

    Salam.
    I have mehran VX 2003. recently i overhauled engine, after overhauling i drove 1500 km. It is giving me 140km on long routes with full cylinder and 110 km on local rout. It has perfect starting and good pick. BUT
    i am facing a problem at high speed above 100 km/h speed it suddenely starts taking jerks, when i release paddle , it becomes normal.
    what is the cause of these jerks and solution plz

    It's Due to Engine (as if releasing accelerator at high speed stops vibration/jerks)

    Bro your car is not making air fuel ratio corectly consult your mechanic he will adjust in a minute.
    I drive most on cng but when i turn on petrol my car does same because on radiator a tape is rounded s that car use 1:5 cng and air ratio.
    Beshak ALLAH he sy hy sub waqt sy pehly nahin zarorat sy zada nahin.
