- 1991 VN V6 Executive Series 2
I was wondering if anyone could help me with this problem. I have a 91 VN V6 Series 2 Commodore Executive Sedan with about 220 000 kms on it. I recently had it converted to lpg (a megagas system) for duel fuel. The problem is it sometimes stalls when you take the foot off the gas (when on lpg) and coast ie when you slow down for a set of lights, turn off, or anywhere really, which can be very dangerous. It seems it happens most when I get a straight stretch of road for a few kms then have to slow down. It is fine under power and I have no problems on petrol. I have recently changed the thermostat (it runs at about the second bar and opens about the third bar on the temperature gauge). When it has stalled, the gas converter is (usually but not always) luke warm to touch though the coolant hoses going in to it, and the thermostat housing are hot (the converter can be hot when driving normally around the city). It doesn't stall all the time when driving around the city, only occasionally when coasting. I've taken it back to the fitter and our efforts haven't been successful in fixing it yet. The next plan is to replace the converter. I often have to crank it over more than when on petrol to start, particuluarly if it is warm. The l.e.d. gas gauge can sometimes go to red even when I have 3/4 full tank too, though this is the least of my worries (I was wondering if it was something to do with the electrics). Has anyone had any similar problems or any ideas on how to fix it? Any help would be appreciated. Thanks.
