    General bad heath . Could be leaking injectors, dodgy fuel system, something like that. Depends how long since you gave it some love

    rooboy, if you have a dual fuel it will be tuned for optimum performance on either gas or petrol, it cant be both. The engines were never designed to run gas from the factory, so if you tune it to run gas smoothly, its not going to run petrol very well anymore.
    The hall of fame:
