Maybe check the contacts on the affected coil/plug for corrosion? Might be preventing a good connection to the coil.

okay payed a mobile mechanic to come out today, he plugged in the scanner in and got error codes all relating to cyclinder 4.. ( the affected cylinder ) - Coil is good, cyclinder is good, injectors are good.. looks like the problem is the voltage its delivering to the coil.. should be a stready pulse but sometimes the pulse misses.. he could not fix it, said its probabaly a faulty ECU and to take it to holden for further testing...
