Hi all. Just registered, had a bunch of Holdens over the years, currently driving a VX2 V6 police pack with factory LPG system, 217km, that we bought a few weeks ago. Just took it on its first decent drive, and emptied a full tank of LPG, and got 9.5L/100km, which is pretty amazing for NZ as we have no long highways around here. At low revs, any gear, with "light acceleration" it hesitates and misses a few times. This happens MUCH less with absolute nana-acceleration, and slightly less with moderate acceleration. It is more noticeable on petrol than it is on LPG. Idle on petrol is perfect. Idle on LPG is slightly rough sometimes. Other than that, drives/runs great, and ~700km from a tank of LPG in NZ tells me its certainly burning the vast majority of its fuel well. Where to start? Is this a simple airfilter-then-plugs-then-leads-then-coils replacement affair? Or does someone here recognise the symptoms as being something specific?
