Nothing needed to be fixed, that is why i spent 3k getting things replaced professionally such as the gas converter, updated gas computer, inlet manifold, radiator, ignition leads ect. on the engine to ensure it wont breakdown. Trans is in good working order have had no problems.
Does the vehicle come with a roadworthy covering the lpg system too .It hasn't been legal to place a lock off in front of the strut tower since 1993 ???? and the position of the converter is at best questionable ???
