Ok,

map readings are idle 340hpa-misfire 260hpa-4000revs 210hpa

gas readings
o2 readings and hc readings are practically zero at all times

Tick over is co 0.003
L 1.000
CO2 14.96
Misfire CO 0.027
CO2 15.28
L 0.998

What has become evident today,is that static,with a warm engine,it will miss right up through the rev range,providing you get the throttle position/load just right,i.e just leaning on the throttle.

Thanks
