Loss of power in my SL
I have a 95 SL500 that was running good when I came home Thursday night. Friday afternoon when I started the car it seemed to be running rough, I just thought maybe it was cold from the temperature drop. As I drove there was and still is a noticeable drop in power as if I'm using 6 or even 4 cylinders. At one light I put it into neutral and put my foot on the accelerator to keep it idling. I removed the old F8DC4's and installed Platinum +4's and now my check engine light comes on. The car runs a little smoother but I still have no power, could this be a coil problem?
Any help is greatly appreciated.
