Hi, I have just had a new install of LPG (now duel fuel) in a VT V6 wagon. I now have a problem where the car will stall when on gas after about 100mts if the engine is cool (ie in mornings or after being stopped for 30mins). If i start the car on petrol and go about 1km then switch to gas all is fine. the car runs smoothly on both gas and petrol once going.
So for the fitters have replaced the lpg computer but problem is still there. any advise would be great..

Thanks Rhys, i'm not too sure if freezing is the problem or not. The mornings are not that cold at the moment and this even happens in the afternoon. If I keep the accelerator at a constant force the revs will drop until finaly the car stalls, but the c Edited by user Sunday, 7 October 2007 3:10:45 AM(UTC)

Hi Shane,
Yep, I should have re-phrased wat I wrote before - Instead of "cold morning" change that to "when the engine is cold." Even on a hot day and no water flow through the converter will make it freeze. Idling isnt going to make the converter free
