Why is Check engine light on and my car riding rough/shaky with a putting noise?

Hello, your concern could be caused by many possible causes. An ignition system misfire could be a cause. Improper air fuel mixture. An exhaust system that's plugged. An emissions system with concerns. The possible cause list is too long to create a good guess. Therefore proper testing will be needed to find out what's going on - hands on using a Volvo compatible diagnostic tool and referencing workshop manuals from Volvo to guide towards finding the fault.
