Wierd issue, this...
If I'm cruising along, and pop it out of gear, and start to brake, the revs obviously fall off - but rather than fall to idle (~800 RPM), it falls a bit further (~600 RPM), which makes the engine quite harsh (akin to being on the edge of stalling).
Once the car stops, the revs stay at ~600 for half a second and then it returns to normal idle.
And all of this is while out of gear
Any ideas? Car idles fine, if I pop it out of gear but let it coast it idles properly as well.
