    most probably it will be a clogged fuel filter,
    if not check fuel pump / injectors etc...
    Life is short and very unpredictable just like a Quarter mile .....

    Default Ultrasonic fuel injector cleaning

    Whenever an engine is turned off, the last drop of petrol dries on the tip of the injector. Continuous evaporation of petrol on the nozzle of fuel injectors form scaling which disturbs symmetry of fuel flow and spray pattern. This results in hesitation, missing and stumbling of the engine. Pickup and power are lost and the emission smells of unburnt fuel. Injectors are very sturdy mechanisms and don't fail very easily. There is no need to replace fuel injectors unless they are really gone bad. We usually replace our injectors with Kabuli or second hand injectors which themselves are sometimes clogged. Injectors are designed in such a way that they are not very convenient to clean they are sealed units and can not be opened for cleaning purpose. Ultrasonic cleaning is internationally accepted most effective treatment of clogged injectors. It restores the injector to like-new condition and bring back engines power and economy. I represent FI-Tech which takes pride to announce ultrasonic fuel injector cleaning service for the first time in Pakistan.
