If you're running on LPG my bet's a spark plug gone bad and causing corona ringing / arcing.

Also suggest using only copper core type spark plugs for LPG, as these have better conductivity. I've found NGK and Bosch both very good.

AVOID long life iridium and platinum electrode plugs as their low conductivity shortens the life of coil packs and HT leads.

Would not recommend much more than 36k for a set of plugs on LPG - it's a much tougher life for them than running on petrol.

Very likely you'll find one plug insulator that looks burnt or has arcing lines on it - hope so in any case 'cos it's the cheapest option!!

You'd be amazed how many "FVSH" V6s still have their original plugs in at well over 120k - I've seen some with hardly any electrodes left!
