I drive a 2003 Pontiac Vibe. I employ Engine Off Coast(EOC)ing regularly during my commute. I've noticed that, more often than not, my idle speed is up around 1200 RPM after bump starting at the end of the glide. Once I purposely let it idle for awhile (seemed like an eternity!) and it did finally 'relearn' and idled down.
So today I tried something. I keyed off a SECOND time (for about 2-3 seconds) during the glide. Bump start like normal at the end of the glide and...

Viola, idle's fine.

Then I just keyed off a little longer the first time, and it accomplishes the same thing. Nice low idle after the EOC. Apparently turning the key back to 'run' too soon affects the idle for some reason.

Anyone else experience this?
