I have a 3.0 litre 24v shogun that seems to have developed a miss fire at low revs when running on LPG.
What would people's recommendations be.
I don't know when plugs n leads were last changed as I've only had it a month or so.
Could these items be the issue?
What shud I gap the plugs at if I renew them?
Thanks

check in the dark with engine running to see if you can see any arching out

along the leads .. plugs could well be the most likely cause as they tend not to get

changed often due to the hassle of doing so ...gap new plugs to 0.7 ... does the miss fire

show on petrol too as any problem on petrol will be tripled on lpg, system may also

benefit from a tune and a new filter ..... Wink
