I ended up getting the right ignition coils in the end. Actually was lucky enough that one of their workers lives in a suburb near me and offered to come and swap the parts after I got home from work..
Definitely an improvement, engine has more (little bit) torque/power across the entire rev range, runs smother too and better throttle response. But it didn't cure my "3 cylinder startups".
Next I will replace the high pressure fuel pump cam bucket, got the part already and will be fitting it this weekend. Car's done 117000km so about time.. only option I have left really.. if that fails I have no clue as the car never miss fires when driving after that "3 cylinder BS is over just after almost every startup hot or cold".
