Code P0670? Computer?
 

I checked my codes again today because of my engine miss/stutter at WOT. I came up with the code P0670, it comes up as a Quad driver module fault. And it says QDM 4 Fault for this same code. Does this mean that my computer is shot? I didn't think I would see these types of symptoms with a bad computer. Any thoughts??????????
