You need to check the gap as it is very very important in regards to firing on lpg. Your system is different to mine as mine is a teleflex but mine also has a map pipe. The map (manifold absolute pressure) goes to the manifold, use a mirror and have a look for a place on the manifold that has had a nipple added. If the pipe is supposed to be installed there will be a place for it, just have a look, mine goes to the top of the manifold where the pipes join into one.
It could also be on a T piece if it has been tapped off something else.
Kind regards

bit of an update, removed cat today and it was not blocked in the slightest, looks like new, the wiring to the o2 sensor plug was not pushed fully home, van is now slightly better running wise.
i think somebody has been here before!!! i have ordered spark plugs for petrol and lpg and 2 ignition coils. lets see how i get on.
they are the pencil type coil and apparently the engine is a mazda L engine, also used in the ford ranger.
i have read the codes and although non are coming up, it still has a slight misfire so hopefully i am getting closer to resolving the problem.
thanks for all your help and input tt, i will update once i have moved forward with the repair, hopefully it will give someone else a help if they too are struggling with this type of fault.

I have been having the same problem and was wondering if you ever got to the bottom of it. Misfire on cylinder 4. Replaced plugs.. still happening swapped the coil...still happening. Just ordered a new set of coils and a new cam sensor (even though ohm reading was OK) but waneed to be sure as also have very delayed accretion. It happens while running on lpg and petrol so thinking it must be an ignition or timing problem.
If you ever worked it out or anyone has any tips, I would be great full for some pointers. Cheers
