Bit of an OLD thread here. Fixed some years back. Was an issue with the "coolant" lines, a bit of a BODGE job by the MEH installer, which are used to by the vaporiser to convert the LPG liquid into a gas, as such it was like the system was starved by fuel causing the misfires

Everything appeared fine, apart from the engine codes, it was getting fuel, but not in the right form to spark properly!
