Classic Saab 9-5 (MY 1998-2010) / Zero misfires? Surely that's not right?

I was preparing for the service & MOT next week, and connected the Tech2 to further investigate the airbag issue. So, while it was connected I ran through some other bits as the engine is vibrating on tickover and a bit above.
The Tech2 is reporting absolutely no misfires. None at all. Which is, to my mind, not right as misfires are normal. I'm suspecting a DI or ECU fault. Any thoughts?
