Hi I have got a 2003 ford transit van 2.3 petrol/Lpg factory fitted. The problem that I am having is that it is missfiring on the LPG side and nobody can tell me whats wrong with it? I have had it serviced, put in new spark plugs, put in new induction coils, put in new wiring loomes and installed a new duel fuel control module. But still it does not work? Any ideas?????????
