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

Run some carby cleaner thru it if you don't regularly use petrol on a gas motor the injectors will gunk up with crap and also your rubbers (as in diaphragm and such) will perish also if the carb cleaner does nothing try new injectors maybe pinch some off a mate throw em in and test it?

thanks for the reply. i bought a set of au injectors off ebay and put them in a few months ago then a guy on here said that could be it, cause there were some cheap s**t ones selling on there and yeah turns out that shat them selfs i put my old ef ones back in and its fine now, dodgy s**t off ebay!

Haha was meant to warn you bout buying eBay poop injectors
