Hi all, My series 3 2.25petrol has lpg fitted with one tank in the back of the swb with a gauge attatched to it. Costs about ten quid to fill and does about 30 miles from full to quarter full then needle starts swaying up and down (quarter to empty) and it starts to cut out.Also when engine is hot i cannot start again on gas have to switch to petrol to start.. Is this normal or is the gas setup wrong has anyone any ideas on this. How many miles should i be getting to a tank of lpg.
Thanks Adrian Ford
