Cool cheers mate,

So at low Kpa, and low load lots of advance is alright, i guess that makes sense thinking about it!

Yea your right mate, the fact that its 3 cylinders mean its either the sub loom or the injector its self.

I'm going to buzz the pigtail loom through this evening, i guess cylinders 2,3 inject together?

Have you ever given the live VE analyser a go?

Rob,
