im not to sure i have only had the car a month ,, well what happens is normally at about 70+ mph or hardish acceleration the car starts to missfire and lose power and will continue to missfire till the car is pulled over switched off but when started again it will run fine untill up at speed again or hardish acceleration :S ??
I have a 03 plate 2.6 v6 mig with a brc lpg onversion and encountered much the same problem as you. misfired at speed and eventually wouldnt stop misfiring (fault codes misfiring on 3 and 5). turned engine off and removed key before changing over to petrol only. car ran perfectly with no misfires and concluded that it was an lpg injector problem, got a couple of new brc injectors £55 each (after eventually finding a brc fitter) and car worked as it should on gas and petrol alike for about 6 months and it started misfiring again on both lpg and petrol this time(same error codes) and had to keep pumping accelerator before the car would start. went to a garage i know and had the 2 coil packs replaced. old ones were corroded and cracked with oil from the rockers and rain water sitting in the wells. fingers crossed the car drives like a dream now. well i have one slight problem and that it still has difficulty in starting when on gas but start using petrol and change over manually when car has started. but that is nothing compared to loss of power and misfiring. hope you get yours sorted soon.
