For those with LPG (or thinking of converting to LPG) the following link is very useful:

Also from my experience I think the following is worth mentioning (which is clearly stated in the link)
You MUST have as close to standard and new as possible all components in your ignition system. since converting to LPG (now some 4 years ago) I think I have tried loads of aftermarket bits but in the end what works best is toyota distributor, leads air intake (you can still remove some of the bends and other bits but keeping the airbox/filter and AFM seems best). Also the most bog standard plugs possible (NKG) re gapped to 0.75mm.
Mine was just staring to run a little rough again and I just replaced the plugs (did the leads, air filter,distributor cap and arm last year) and its like new again.
Cheers
