The only hiccup I've had in the last 1500km since the harness recall was when the engine shut off when I pulled in the clutch approaching an intersection. I haven't bothered worrying about that too much. Otherwise I haven't had any repeats of the low idle, rough running behavior I had before the recall. And my idle has always been close to 1400rpm, and I typically get 39-40mpg, both before and after the recall.
