hi
i own a lexus ls400 1992 with a gas/lpg conversion,running on petrol is fine but when i switch to lpg the engine idle speed reduces then cuts out.When i`m going along its fine on lpg but when i come to stop the engine cuts out and wont start again till about 30 seconds later?I was told this was to do with a lambda sensor but this has not cured the problem.i`ve been told to put the car on a diagnostics machine to find out the problem and i`ve also been to a lpg conversion place which costs the earth for their services,and still the car doesnt work properly.I`ve been told the conversion kit is italian made to which i beleive is good.Has anyone got a cure for this !
