I can't confirm that that applies to all FI cars.
In my downhill run, the exhaust on the Clunker burbles slightly when engine braking and the vacuum increases slightly (and engine braking increases slightly) with the key off. This leads me to believe that a small amount of fuel is flowing. This is a '90 with PGM-FI.
