I think the MAF is the culprit, when going slow on a roundabout or junction the rpm is in the region of 700ish the MAF reading goes up and down from 25kg and when the car starts to “hunt” it goes down as far as 0 for a second or so. As soon as it...

Although I agree it's unlikely to be the IACV, worth checking & cleaning anyway. Are all the LPG hose secure on the manifold ? Prob worth cleaning the throttle body & checking for leaks there as well.

They read as ok

Are the o2 sensors good?

I can't say I have, I didn't really consider that because she runs as smooth as silk up to and after these episodes

One thing to add is that it only (so far) does it at slow speeds, no misfires or hesitation when going faster, it does hesitate a little if booting it but then it always has so I usually put it in sport mode and it boots down fine.

it happens when running on lpg? so it can't be the fuel pump or rail pressure. you can unplug the maf and drive without it, but it doesnt sound like a maf problem also unlikely to be the idle air bypass valve i think you need to see the injector...

HT leads/plugs are 2 years, coil packs as far as I know are AD 1997 :) I have had the old girl since 2010 and I haven't changed them prior to that my brother had it for 4 or 5 years and he certainly didn't change them. It does it either hot or...

Hmmm, if it only did it hot I would suspect a crank or cam sensor starting to go. It may still be. How old are the coil packs and HT leads?

All other electrics are ok as far as I can see

Check crank sensor & connector. It's down the left passenger side of the engine, & a common location for oil or moisture to get in. When it dies, do other electrics cut out as well ? I had an issue with the main battery connection on a...

The fuse box is pretty new TBH but I will take a look and see, I do have a spare to try too

Thanks Pete, so far no faults logged which is why I am scratching my head

I am not sure if anyone can point me in the right direction but I will ask. I have a 98 4.6HSE which has a random issue. Sometimes when starting it dies immediately or chugs a little and then runs fine (hot or cold) most times it starts and runs...

I suspect those tank O rings may have never been changed since new. When I replaced the pipework a few weeks ago, I probably disturbed them and that's when they started leaking...

We all knew you would get it in the end :)

Well after giving me the run around for a few days I think I've got to the bottom of it. I swapped out my valve block for a re-furbed one I had on the shelf, and also cleaned up and renewed the o rings on the drier that I observed bubbling with...
