Just found my annoying intermittent miss !!!
Fuse is cracked and is only affected when running,
Number 3 which is coil and injectors .
Throw these out and replace.
With the annoying fuse issue now sorted ,there is a bright side .
Iac valve is now removed and a map sensor installed using the same vacuum hose through the power commander unit .
Should by dyno tuned next week
Keep you posted
Cheers
Paul
