Scroll down to the EF. And don't we know about this little problem. If you don't you've NEVER owned an 'E' car.
I think it might have to be standard practice. If you have idle, flaring issues. Get the injectors cleaned properly, if the ECU idle drivers are gone, get a new one, new leads/plugs and an inspection of the coil pack might be the go.. :P

stuff it, here it is for all to read.

The EF is developing a few idle problems. Most common is dropping the odd cylinder at idle. Appreciate the EF is the first of the really lean Falcons - 90% of the problems are dirty injectors - they are NOT like the previous models that can idle with filthy injectors. In the EF this will lead to ignition lead and/or coil problems. We strongly recommend the genuine leads - they last longer and appear less prone to cross firing. The coils should be tested just like on the V6 Commodores - that is, they should be able to jump 30Kv or 1" in atmosphere when you add in the gap. Coils available from those fine chaps at FUELTECH for less than $100. The other common problem is the severely flaring idle - sometimes as much as 2000 rpm. While we have had a few problems with the idle speed motor sealing (usually only flares a few hundred rpm after high manifold vacuum) most common is the idle speed motor driver in the computer. This is the EF that stalls or screams its head off for no reason - makes it a b**ch to drive around town. While there are a huge number of different EF ECU's, we can now supply overnight for $300 if we know the part code affixed to the harness plug - 94 DA 12A650 xx (where the xx tells us the application).
