I own a 2012 s60 five cylinder turbo and the dash had the check engine light on for about a week before I could get the car to the shop. I had the OBD2 read at O'Riely's and it said that I had misfires on cylinders 1,2&5 and random misfires. I replaced all of the cylindrts and the misfires continued. The car after driving it for two days has gone into safe mode with the "reduced engine performance" message on and the car won't start. Should I replace the coils and get new spark plugs? Heeeelp
