G'Day guys, I am a very proud owner of a Gold TL Magna ES auto with dedicated LPG. It is running smooth and quite trouble free. There was a couple of times that when I move on from traffic light, the car suddenly struggle at second gear and change back to first gear. Then I tried to use +/- mode and see if it helps but when I change to second, the engine feels like run out of gas and putting along. If I change back to first, it runs but engine rev really hard. Then I pulled aside and turn off the car and restart again. Then it was normal after. Anyone have any clue why this happens? The auto gearbox seems running ok and I own the car for five months and only happened occasionally (twice), does it have something to do with dirty gas? Thanks.

dont know much about the gas conversion

but most problems are at the switch valve form gas to fuel

or at the gas regulator

you need a specialist in gas

untill then run on fuel

Hello there, thanks for your response. I will see a Mitsubishi dealer and sort the problem out. By the way, this Magna I have runs on dedicated gas, not dual fuel. My mechanic just phone me today it could probably is dirty gas which makes sense. I did fuel up at Safeway on both times when that happened. Once again, thank you for your response!
