Hello,
This goes in the unusual repairs. I have had several 2003 9-3's that would have either misfire or overboost codes after all 4 coils have been replaced and it has actually been an T8 update that was never performed. So you could have someone with a Tech 2 and SPS programming see if an updated T8 program exists for your car. I have also seen many of these cars with corrosion on the combustion detection module connection from coolant dripping in them but cleaning the corrosion or replacing the combustion detection module has never gotten rid of any codes. Good Luck, Bernie
