Ok i forgot to update this, but anyway
Took it all apart, which turned out to be a royal pain in the arse, few bolts were stripped so spent ages taking them out... anyway
Gapped the plugs
Checked and cleaned all coil packs
checked earths
took for a run, and there was no change.
unplugged solinoid, hardly any different.
put it all back, scratched our heads... ended up cutting the wires to the UniChip and wiring it all back to factory, but still be able to plug the UniChip back in.
Took for a spin and no more mis mis, well till real high in the rev range, which we later discovered was due to it only having 91RON fuel in it!!!!!!!!!
So plans are to get it down to hobart and put the UniChip back in and have it tuned to 95RON, with more sedate timing
