Ford ef xr6 is missing on fuel but runs ok on lpg, ive just changed the map sensor is still doing it, last time it did this it was the hose that goes into the map sensor that blew off but this time it was fine? any ideas of what i can be? its got fairy new au injectors in it, new fuel filter, it still runs on fuel just really rough and is missing, any ideas on what it could be?
thanks
