Guys - my diesel has always run smooth under power, just shakes at red lights. But not for the last few days. Smooth as a baby's buttocks. Why - I have no idea. I like the idea of an idle stabilization fuse; with the answer had been that simple all these years.

It will get hot in Atlanta again and I will get the shakes again; sure as anything.
