Is there any reason why replacing the DME relay would smooth out the idle?
I had a bad vibration at idle which disappeared at 1500, and I was certain it was caused by bad motor mounts. I then replaced my DME relay with the Focus 9 solid state relay, and the vibration has just about disappeared. Coincidence? Why would that be the case?
