Update:
So, I changed to the Ford coil pack, and Iridium plugs (as suggested)
No real improvement, although seemed to idle better!
So, I added 3x4.7uF poly capacitors between the live of the coil and the earth.
No improvement.
So, I went around tidying all the wiring, moving sensor wire paths away from ignition, injection and alternator wires.
No improvement. Actually slightly worse!!!!
So, swapped plugs to non-Iridiums, tied down more cables, and discovered the power output from Alternator was loose
Problem solved. I think the cable was flopping around at the problem RPM which was giving some nasty spikes.
Reved up to 10kRPM on boost no problem. Seems to be working now.
Only problem, is that I have water getting into the oil, so need to sort the head gasket out. E-bay barrels and pistons, looked okay, but I guess
they needed a skim.
Never mind.

Thanks Mike,
1 step forward, 1 step back. My oil breather catch bottle was full (I mean to the brim) with mayonnaise after the last run.
But I've got enough engine parts kicking around the shed to build 3 engines*.
Matt
*all of them as dodgy as the last 3 that I have built!
