Drove my Omega today,and it definitely had a misfire and a lack of power on LPG at around 2k rpm.Switched to petrol and it was fine.
Might try changing plug leads as I have a spare set.If that doesnt work, my recently replaced dispack "thought to be a good one but not certain",may be suspect. Other than that - LPG system problem I suppose. :-\
Try Denso plugs mate-mine used to faf about until put those in- :y

An additional factor in carb icing is that sometimes fuel has significant moisture in it, which doesn't help.

With an injection setup, the fuel is out of the picture, but given the right weather conditions (low enough temperature and significant humidity) it can still happen, hence the heated throttle body.

Well it was cold mate but had me flummoxed for a while-did have a mild worry that the old girl was throwing the towel in-I even promised to clean her nest weekend :D :D-Nuts I know but reckon she got mind of her own mate :D ;D

Previously it has always been fine on GM twins.It had new GM twins in the last couple of thousand miles.
Problem started with rusted/split dispack.Changed that for one which looked excellent and was thought to be a good one.So I think its either that or possible the leads. :-\

Mine gets cleaned when there's nothing else left that needs fixing.. It is fully aware of this policy. So, until that PITA sticky central locking motor has been refurbed... >:(
