Right as some of you will know I've been swapping bits over to try and cure the misfire my RS suddenly picked up on the way home frm Trax

So far I have tried swapping dizzy cap, rotor arm, plugs, leads, TPS, dizzy...

2moro I'm changing the chip, fuel filter and maybe injectors, other than that I'm out of options...

anybody got any suggestions as to what it might be?

It seems to be between 2-3k, as soon as it boosts it feels like it clears and goes ok.....

I'm beginning to go mad now, wanted to put a brick through the fooking thing earlier
