Thanks. I'm curious why it's better at driving speeds?

Interesting. I glazed over that part as I read the low compression information. I had a '96 Outback that suddenly was horribly rough during idle, but (like yours) was fine at higher speeds. The problem with that one was a knock sensor. But, the knock sensor failed, which did post as a trouble code (knock sensor out of spec). It ran especially poor when the engine was cold.
