    Default Cultus 2006 VXR - Jerks and eigine sound

    I have Suzuki Cultus VXR 2006. The car runs very well and goes upto 150 (CNG) on average on motorway.

    At pick it jerks a lot. And when running it jerks like you have applied 4th gear at 20KM/hr speed and the car suddenly wants to switchoff. For understanding of the problem note that jerks like you applied breakes running at 100km and speed is down to 20 but you have not changed the gear and car will jerk. It gives jerks like that even speed of 80 in 4th gear. Then I have to lower the gear increase the speed and again it does so lower gear again incresase speed and apply the next gear to cater the problem. I cant use 4th gear at 70/80 km/hr speed.

    May some one suggest me what the issue is and to whom i should consult. I went to Suziki Azim but they just tuned up cheked RPM and said ok but the probem still exists.

    Engine sound is very bad like a tractor.

    Help please.

    This problem usually arises because of faulty spark plugs,defective ignition cables or ignition coil and too advance ignition timing,get it checked accordingly.
    Never loose hope in life,every step gives u something.

    ^^ I beg to differ slightly. In my case, a too advanced timing only causes engine response change. As in, the engine gives good response at low end. And gradually saturates out at about 4.5-5k rpm.

    Yes the plug wires can also be the issue. But that can be felt at any range as soon as the engine is commanded WOT.

    But the first most common reason for this in Cultus 3 cylinder is that the CNG is too rich from the T-bolt. That coupled with retarded timing.
