I think we do. I have binned the lpg as i fitted a new engine and when started it the engine was miss firing checked and changed plugs coil pack and anything else i could think off. i decided to cut the lpg system out and had to rewire the injectors proper pain in the arse. Turned the key and run sweet as a nut. New engine cost 400 buks and only had 62,000 on it. Old engine had done 142,000. I hate to think how much i spent on gaskets and everything else before i bought the engine.
