Feel for ya Bro,
there is nothing more frustrating, when this then that with little result.
and a truck load of $$.

seems it's not your problem , maybe worth a mention anyway, ya never know !.
My sons GQ tb ,also lpg, has a Genuine Nissan dizzy cap and it runs as smooth as a baby's bum,
people have commented how well it runs and starts.
tuned by me 12 mths ago, and I ask regularly how it's going, "still good" .
there maybe something to Gen product ver's aftermarket.

Ver's Mine has a slightest of miss,cant seem to tune out.
might talk him into swapping parts to compare.
will post up results afterwards.
Hope ya get it sorted soon.

Yes its a bitch as its stopping us from using the boat in this great weather.

Have had a set of the top dollar bosch lpg compatable ign leads fail within about a year.

I thought the same thing too but pezzer has only just recently swapped from a carby setup to an efi setup.

Yes definitely no leaks, still have original dizzy cap and rotor button.

G,day, I gota 4.5 EFI petrol.
Had a miss at idle even after service, plugs, leads etc.
Got my tappets adjusted next major logbook service.
Rough idle/miss is gone?
Worked for mine, Maybe try that??
