Budgie:
When was the last time you put injector cleaner through the fuel system?
Does it still "pop" through the air box when the revs are constant, rather than being blipped?
Are you hearing any tapping noises from the hydrolic tappets, you could have one that's blocked and not at the correct setting.

SteveGoodz:
Well it certainly sounds better with everything connected up  :D

Just a wild stab in the dark but how about a sticking injector?

disco-v8:
used to put injector cleaner in every 2weeks but after i bought new injectors not so long back, i cut down alot, only used it a couple of times with the new ones.....

as above i wouldnt think ive got a sticky injector as there are brand new injectors.....


dont think it does pop on idle only when the throttle is reved but it never used to do it and its always worth trying to sort it out before more damaging things happen to it...... im possitive its not ment to pop like that

Range Rover Blues:
All engines missfire a little, TBH if it's trying that hard to run (ie in peices) then I'd put it back together and stop worrying.

Try
check plugs, grade and gap (close up to 27 thou for LPG)

Leads for cross-arcing

Dizzy cap, lots of rubbish ones about, check that all 8 terminals have discoloured/pitted the same amount, check for cracks and tracking.

A richer fuel mix is harder to ignite, like LPG is harder, so a slight weakness in the ignition will show up first under acceleration.
