Yes it clears under acceleration mainly bad between 1000/1500 rpm, rotor button is good, no air leaks as far as I am aware. I will check plugs today just awkward to get to with LPG fitted.

Is your condenser freezing over at all ??
Also squirt some WD40 inside the dizzy and on top.
You may have condensation under the leads on the dizzy
You could remove one at a time to check, make sure they got back in correct position
and push them all the way in

Yes I checked this, I believe now possibly dirty injectors, I crimp the return fuel line and it rev'd which to me shows a lean running motor pressures seem good vacuum on fuel regulator strong with no signs of petrol seepage. crimped and blipped it a few times now lumpiness is a slight random miss. Idle is 900 as this seem the best for lpg and petrol to load up and pull away.
Just went for a quick run on the h/way and every time I accelerate it misses.
You could/may still have cracks or splits in the vacuum side of things be it only little

No I have not renewed either just a good clean up and I have a terrific spark so I thought that this was a good sign. No arcing at night visible.
Could be your injectors. Have you tried an injector cleaner? I found fuel doctor actually works, bought at super
Cheap. Have you checked fuel rail pressure? Should be 40psi. When I bought my patrol it measured about 32 psi. Changed the fuel pump and it jumped back to 40psi and made a world of difference.
Edit: forgot to add, if you have a vacuum leak, an obvious sign is a "putt putt" sound at the exhaust.

No vacuum leaks, I will check fuel pressure and get some fuel doctor. THANKS FOR THE HELP EVERYONE.
