odd question i know, but not sure where to look this one up. in many vehicles when engine breaking over a longer distance (such as down a hill) the ECU will simply cut out the injectors to save fuel. the forward momentum is used to keep the engine turning and everything working. very useful down a large hill, just gear down and you use zero fuel to get to the bottom.

not sure of accents have this feature or not - some refer to it as DFCO.

 

I don't know, but judging from the popping I get my guess is no.
