I have a LC3 on petrol & LPG , for the past 15 months it has been baffling myself and 3 garages as to why it has an electrical missfire on both fuels , it may go as long as a month or 2 with no problem then watch out! Recently , on 3 occasions it has actually stalled and failed to restart . It is definately worse in wet weather . The 3 garages have plugged it into their computers but all it throws up is multiple missfire ! I am starting to loose faith with both the garages and car . please can anyone give me advise ?
