misfires

[jrtb]

V8 disco misfiring and hesitating on LPG
What do I replace first?
Plugs and leads?

[jjsaul]

have u got flametraps (or is that a carburettor thing...) anyway if u have, clean them out.

if not check ur plugs and leads.

plugs AND replace with gas compatible leads (often people don't use them). If that doesnt work, look at rotor button or go for all round attack and do them all anyway.

Worth a check.

Mine misfires regulary and its nearly always the the little screw on caps on the plugs (where the lead clips on to) that have come loose....

Yes i do tighten them, and then still come loose (may be heat related)

Normally when my LPG V8 starts misfiring I replace the plugs. My the gap a bit wider than specified. Also I anoly use NGK... for what it's worth.
