You say you have changed plugs... are they gapped correctly?

Also is it a turbo?
my turbo does the above if i try to run it on unleaded, Has to be Vpower on mine...

Yes i had the plugs changed as it had a misfire, was done by my father in law a mechanic of 25 yrs and yes it is a turbo run on V Power too!

does sound like plug gap.

did the father in law work on turbo cars? run a lot smaller gap than NA.

In that case i would say as above,
Check the plug gaps mate
The misfire could have originally occured as its not uncommon for turbo engines to melt a plug,
Fitting new plugs which are not correctly gapped will cause a very similar misfire.

When i serviced my old S14 turbo i was unaware what the gap should have been,

Standard out the box plugs are normally about 1.1mm, not sure what the scoob is but I needed to regap mine to 0.7mm because as soon as boost was kicking in i was losing spark and misfiring,

As above, recheck the plug gaps. If your happy that they are correct, i think 0.7mm for the gap size, i would try and rig up a gauge to check fuel pressure while on the move as a dodgy fuel pump could also cause these symptoms.
Cheers,
James.

Also make sure there are no kinks in the rubber hose leading to the fuel filter, long shot i know but i also had that issue lol
