CEL Light and low power any ideas?
 

As the heading suggests i have been using my 2006 impreza wrx today and was all good, got back in it this evening and the cel light was on and the car has lost power noticeably, no smoke, smells, or funny noises so I'm at a loose end, guess il have to diagnose the fault code but just thought I'd ask if anyone has had this!!
