ae86 misfire!

[cork kouki]

sounds like it is the dizzy, but as stated above by sc, could be a few things that give you that problem.

i`d start with the ignition timeing if its def not the tps.. no harm re setting it anyway.
only take 2 mins.

Surely there isnt much to go wrong with the distributer itself though bar the timing bien off?

worn teeth, rotar tip been worn causeing misfire at high revs...

cause they rev so high and up irish feckers love the sound of a screaming 4age i think you`ll find we can break almost ever part of a 4age engine

Check all the vacuum pipes as if there is any pinholes it could run like shite. They could be worn down I had similar problem

[tweek]

As a matter if interest what did you clean the plugs with?I hope you didn't use a wire brush on the iridium tips

Ermm ya used a wire brush iv new ones on the way though

getting loan of a timing light there later too, so should hopefully have timing set right this evening

[cork kouki]

sorted the timing today, didnt make a whole pile of difference

I got a spare engine with the car and a load of other bits just have to pick it all up yet,
hopefully there is a dizzy on the other engine to try

sounds like something electrial breaking down under load... Coil, plug leads, new plugs, connections on tb sensors, broken or damages wires making bad connection
