Stator or voltage regulator / battery? Have you tested the charging system to make sure its producing enough voltage at the lower RPMs? It could be that below 3k, it just doesn't have enough juice to fire all cylinders consistently...especially if the battery is low. Have you checked the spark plugs and the cables?

New battery plugs seem ok but will get a set as soon as shops open on Tuesday charging rate as it should be I suspect it to be an injector but no way of testing them will try when I get plugs just wondered if it was a common fault

Good to hear you got it sorted. :thumbsup:
Was it bad gap or bad plugs all together?

I was gonna suggest, the other day, that you pull the plugs one-by-one to try to narrow down the fault, but figured you'd already done it.
