what type of air filters do you use when running lpg?
is curios why i ask this look in the how to tune topic

.... as i changed my filter yesterday to a cheap one. and the car idled lower and rough. I increased the sensitivity and it improved 9 havent taken it for a run yet but idle is better. i noticed earlier that the idle bypass valve is always open when on lpg. my air fuel meter is still reading rich at idle so i am thinking that I need more air at idle that a au 2 just on petrol would need to idle smooth so a better filter or a bigger idle bypass valve. any observations on filter changes ie from stock to high flow or back the other way wold be helpful
