About 1/2 a mile from work it switched to gas all ok. Then I got to a junction pulled out and it stuttered and cut out. Eventually it stuttered back into life and was fine! Airlock?!
Now on 300 miles and the low gas light is on. Sounds about right I guess. I will fill up tomorrow and see if I can get any in.
Not having much luck so far!

When the LPG is running low (in my car atleast) you should notice that the car will just not accelerate with any gusto.About 1/2 a mile from work it switched to gas all ok.

When it is really empty, it will stutter and even 'backfire' (blew my mates airfilter housing to pieces in his VW Jetta).
So far, i am loving cruising on gas

I think you need to get back to the installer for a check up - perhaps they need to do some fine tuning. About 1/2 a mile from work it switched to gas all ok. Then I got to a junction pulled out and it stuttered and cut out. Eventually it stuttered back into life and was fine! Airlock?!
I had some running issues in the beginning but that sounds a bit off - on my Prins system it was running a bit 'jerky' when creeping in traffic so it went back for an overnight visit so they could tune it from cold. They hired me a lovely courtesy car car too - a 1.4 Corsa if I remember correct - made me appreciate the 330 even more!
After that it was fine (except for one time when I was cornering very hard and the system switched suddenly switched from LPG to petrol along with the associated cut-off of the throttle as it switches over - it unsettled the car a bit is all I will say! Turns out the LPG level was low and when I slung it into the bend and the gas went to one side and therefore the system thought it was empty and switched to unleaded. Not really a fault with the system as LPG is designed for economy drivers, not hard cornering. So when going at it on some twisty bits I made sure it had enough LPG or just switched to unleaded)

Run to empty, fill. Zero trip, run to empty.
I'm of the understanding that running to empty on gas regularly -which I realise you're not necessarly advocating here- is not great for the engine. Though when my car runs out of gas the switch to petrol is barely noticeable, so I wonder how bad is it really? said:

My car will idle more smoothly on gas than on petrol, regardless of LPG level. When the LPG is very low, it will switch to petrol on hard acceleration; other than that there is no discernible performance loss, stuttering or backfiring. I'm no expert, but perhaps your LPG system doesn't switch to petrol quite as soon as it should?When it is really empty, it will stutter and even 'backfire' (blew my mates airfilter housing to pieces in his VW Jetta).
The last car I had with LPG was an Astra Dual fuel.
When filling up you have to squeeze the trigger on the nozzel and press a button on the dispenser too.
Are you doing both?
if you don't press the button the punp will not dispense gas down the tube]
It can be a bit tricky, especially if you have parked just a little too far away.

Just filled up and put in 70 litres into a 80 litre tank!
Car running a bit rough with the engine emissions light on and only did 19mpg on gas compared to 28mpg on petrol!
The fitter advised I change my spark plugs due to a slight misfire on cylinder 1, and if there are still issues then could be the ignition coil.
Your thoughts?
The LED gauges are next to useless. In mine the next light goes out when the gas level drops below that point. In other words, when it gets to just below 1/2 full the second light goes out meaning it looks like you've only got 1/4 tank when you've actually still got nearly 1/2. They don't seem to be able to cope levels in between.
I've had LPG for about 5 years now.
The other posters are correct, the gauges are inaccurate, use the trip.
With regard to the misfire, you cannot use anything other than NGK spark plugs with LPG. Ask me how I know! So if you buy a set of these and fit them, you'll have no further misfire problems.

really, NGK only? Bosch?The other posters are correct, the gauges are inaccurate, use the trip.

The NGK's are over three years old now. To be honest the installer told me I might have to fit them, but to see how I go with the Bosch ones that were already fitted. They started to misfire about a week later. Since the NGK's were fitted it's never misfired.
I wonder what the difference is though? Must be the materials, or the way they're made I guess.
I've had some experience with LPG, and the reality is there is a huge variation in LPG systems, along with a huge variation in price.
When my Father had his chevy Tahoe (for sale, see classifieds) converted, he went with a top of the line system from prins at a cost of nearly £2800 fitted by gas4cars in Woburn Sands (very highly recommended)
a properly fitted high quality multipoint system like the PRINS one, should never stutter, falter, hesitate, pop, bang, smell, loose performance, or do ANYTHING other than reduce running costs and emissions, you really shouldn't know its there.
in Bi Fuel mode, it starts on petrol, and auto switches to LPG after about a mile (about 2 in winter) the only way you know is the green LED's come on, and the orange petrol light goes off.
the gauge is reasonably accurate (although the first LED stays on a little longer than the other three, and if the red one stays on enough to get dangerously low on LPG, it switches back to petrol. it doesn't switch to petrol under hard acceleration, and after 70,000 miles on gas, the engine is like new, the annual oil change sees the oil come out hardly any darker than it goes in.
so many people have been told 'Its just a characteristic of gas' by dodgy installers who haven't set the system up properly, or not installed it properly (i once saw a tank that was fitted with the liquid take off upside down!!!) and with no better knowledge, simply believed it.
single point systems aren't as good, but a good multipoint system should never make its presence known in any way. if you are having any kind of trouble what so ever, take it back, and keep taking it back until its sorted.
