It actually dips a tiny bit below my desired idle rpm and catches itself then idles again. I do still have the flare up when cold or hot. Say for example, I drive the car for 30 minutes, shut it off.....restart it again after sitting 1 minute......it will idle high for a few seconds.....flare up say to 16700 rpm, the drop and idle normal.......any opinions on startup besides trying stock values?
