As I said earlier, I'm not very convinced that the culprit is the IDM in your case.
What you have is a very minor problem where the ECU checks "debit and credit" several times before finally setting the code and turning on the C/E light.
For very small problems it has to happen several times in a row (trip) before the ECU trigger the light.
A "trip" can sometimes take weeks and month before the driver have driven the car long enough to satisfy the ECUs "trip Gods".
So lets say that it takes 3 faulty trips to trigger the light and each trip might take several month to acomplish, it might be a couple of thousands of miles before the light comes on.
To make it worse, if your car have a couple of "non fault" trips in between, it reduces that amount from the faulty ones and you might be back at zero trips.
At this point I can't say either/or if the new IDM finally fixed the problem and you won't be really sure until you have logged some 5-10K more miles on the car without the same problem coming back.
So far on the Saabs I have not seen many bad fuel injectors, but on some Volvo models it is quite common that one injector start to spray lean and burning an exhaust valve.
Saab also uses a fuel injector that needs to be situated in a certain direction for the spray plume to reach the whole combustion chamber.
MAYBE????? if the injector have gotten turned around it could create a misfire like this.
