Engine run-on.

 Once or twice now, in about 1000 miles, the gas engine in my 2005 has
produced a bubump bubump sound with sympathetic vibration when automatically
turning off such as at a stop light.  Sounds and feels like engine run-on
sometimes caused by fuel spilling into the combustion chamber of a very hot
engine.  Curiously, this has happened when the engine was cold.  Anyone else
experience this?

I've had it happen a handful of times in about 10K miles, but for me the
engine has been hot.

It's very common and apparently normal.  See threads at

http://www.priusonline.com/index.php

and

Hmmm.  I get redirected a foreign language site with the first link and find
nothing relevant at the second.  To me "normal" means this behavior is the
rule.  In my case it is the exception.

 

The site appears to be hijacked.



It's hard to find specific information in threads unless there's a good
search engine.


Normal means that it is expected, even if rare, behavior.  Sometimes,
the Prius has that rough idle just before the engine shuts down.  Expect
it to happen at random times when the engine shuts down.  It's not
usual, but it is normal.
