Sounds like you had a misfire and the ECM is warning you to get it repaired before you cause catalyst damage. It could be EVAP related but then you shouldn't of had any running issues that you noticed.
If you are wanting to repair it yourself the things to check would be #1 check for oil contamination from the oil cap seal, #2 check the ignition coils really close for cracks along the boot. #3 make sure it has Volvo spark plugs.
