My Subie started idling high while driving down the road, like it's cycling all over again. I can feel it accelerate and decelerate slightly, but it's getting worse and the dealership can't find anything. Hoping I can figure this out before the Alaska winter kicks in and it leaves me stranded. Anyone have any suggestions? Could it be that something is gummed up? Can I use an engine cleaner in my Subaru? Frustrated in the North,
